Full textThe reaction of chiral primary amines with 2,4-dinitro phenyl pyridinium chloride, according to Zincke's procedure, leads to chiral pyridinium salts which can be reduced with NaBH4 in an alkaline medium to the corresponding 1,2-dihydropyridines bearing the chiral substituent on the nitrogen. Cycloaddition reactions of these dihydropyridines with methyl acrylate give isoquinuclidines in 20-33% d. E. Absolute configuration of optically pure isoquinuclidines separated from this diastereoisomeric mixture is established. On the other hand, reduction of pyridinium salts derived from amino alcohols such as (R)-phenyl glycinol in the same conditions leads to new oxazolidine-type intermediates which can be considered as 2,5-dihydropyridinium salt equivalents. Stereoselective alkylation followed by removal of the chiral auxilliary provides a simple access to enantio merically pure 2-alkyl 1,2,3,6-tetrahydropyridines. The usefulness of this methodology for the construction of optically pure piperidine derivatives is illustrated by the synthesis of (R)-(+)-anatabine and (S)-(+)-coniine

It was known that the Bacillus megaterium Cytochrome P450 BM3 exhibits high substrates specificity to catalyzing its congenital substrates, fatty acids. In this study, cytochrome P450 BM3 proteins were successfully heterologously expressed in Escherichia coli. A mutated Ala74Gly, Phe87Val, and Leu188Gln strain was also validate for octane oxidation. After employing random mutation studies of the P450BM3 encoded sequences, we obtained the other three variants to study their octane activation chemistry without any alteration of P450 reductase encoded sequences. 2-octanol exhibiting a hydroxyl group at the sub-terminal carbon could be further oxidized via the iodoform reaction. The oxidation products were analyzed by GC and UV-visible Spectroscopy. The conversion ratio of C-H bond on the 2nd carbon of octane by bacteria could be quantities facilely and reliably. We anticipate deploying this method for selecting appropriate strains to achieve the C-H activation of sub-terminal hydrocarbon in more specific manner. In addition, the DNA of Pseudomonas putida Cytochrome P450cam (CamC) and Putidaredoxin (CamB) encoded sequences involved with the functions on camphor hydroxylation and catalytic redox suppliers, respectively, were constructed within the protein expression vectors pET 21a and 22b. Those constructed vectors were successfully transformed into the host, E. coli BL21 (DE3). The Putidaredoxin (CamB) protein could be expressed in E. coli heterlogously in the presence of IPTG.

A method to build the framework of bicyclo[2.2.2]octanes via 2-amino-1,3-dienes system with quinine-derived primary amine catalyst was disclosed. According to optimized conditions, cyclohexenones and 2-aryllidene-1,3-indanediones were dissolved in toluene at the room temperature, then 20 mol% of primary amine catalyst and 20 mol% of benzoic acid were added. The substituted bicyclo[2.2.2]octanones, bearing one spiro quaternary carbon and three chiral centers, were obtained in high yields (up to 91 %), excellent diastereoselective ( up to >20:1 dr) and enantioselective (98% ee). This reaction was also operated with cinnamaldehyde, 1,3-indandione and cyclohexenone, through Knoevenagel condensation/ [4+2] cycloaddition in one-pot manner to get desired product bicyclic with the high level of stereoselectivities (>20:1 dr, 97% ee).

This thesis focuses on acid-promoted intramolecular cyclization of O-silyl-protected 3-(3-arylpropargyltosylamino)methylcyclohex-2-en-1-ols and 2-methyl-2,3-epoxy-4-(3-arylpropargyl)cyclohexan-1-ones. Two major reactions are discussed. First, BF3•OEt2-promoted intramolecular cyclization/ fluorination of O-silyl-protected 3-(3-arylpropargyltosylamino)methylcyclo- hex-2-en-1-ols at room temperature under an atmosphere of nitrogen afforded N-containig spiro[4.5]dec-6-ene derivatives containing a C(sp2)-F bond. In this process, boron trifluoride diethyl etherate acts as both the Lewis Acid and the fluoride source. Second, TfOH-catalyzed cyclization of 2-methyl-2,3-epoxy- 4-(3-aryl-propargyl)cyclohexan-1-ones at room temperature under an atmosphere of nitrogen provided 7-benzoylbicyclo[3.2.1]octan-2-one. The Lewis Acid (FeCl3 or BF3•OEt2)-assisted cyclization of the same substrate in air at room temperature afforded aryl(halo)methylenebicyclo[3.2.1]octan-2-one de-rivatives containing a C(sp2)-halo bond (halo = Cl or F).

PART-1 Synthetic studies of the photochromic spiropyran dyes Abstract The major applications for the photochromic functional dyes are in the field of optical memory. In the past few years, these dyes combined with polymeric substrates to form several materials, which could be applied for the new high technology products, such as photochromic sunglasses, color filter, photochromic fiber, or ultraviolet indicator were developed expensively. The major purpose of this study is to synthesize different derivatives of spiro compound(1a).Other carrying vanious electron donating or electron withdrawing groups as R1, R2andR3 characteristics of different derivative are discussed as well. Synthesis of the indoleninium iodide 4 which is key intermediate for spiro compound(1a) is important in this study. PART-2 Synthetic studies of the 8-hydroxy octanic acid Abstract Hydroxy octanic acid(HOA 1) is an inhibiter and it’s very expensive.In 2003, SARS(Severe Acute Respiratory Syndrome) virus wreak people cruelly .This compound,HOA1,was discovered that it could kill SARS virus efficiently. Its function to destroy the microbes was also used to destroy Enterovirus and RNA flu virus. Because of these functions, this compound was used to make the products which can protect people’s health from virus. The purpose of this study is to design the compound methods for “HOA1 ” that focus on using inexpensive materials and simple reaction steps. Furthur more, it will address the possibility of industrial products. .
