AbstractThis paper reports the use of rhodium (Rh) catalysts for the oxidative coupling reaction between phenylacetylene and benzaldehyde derivatives via C-H bond activation. These reactions were catalyzed by Rh(l-amino acid)(cod) (the l-amino acid is l-phenylalanine, l-valine or l-proline; cod is 1,5-cyclooctadiene) to obtain chromones in 12.7–88.3% yield. These new Rh catalysts have excellent activity for the coupling reaction between phenylacetylene and different benzaldehyde derivatives.

Abstract:

In order to graft β-cyclodextrin onto chitosan fibers as more as possible, amino group of chitosan fibers should be protected by benzaldehyde firstly. Based on the similar structure of chitosan and cellulose fibers, different experimental programs were employed to discuss the possibility of β-cyclodextrin grafted onto chitosan fibers in the similar method. By infrared spectral and UV–visible spectroscopy analysis, the results showed although benzaldehyde could be grafted to chitosan fibers successfully to protect amino group, β-cyclodextrin could not be grafted further.

Attempts to hydrolyse the nitrile group of 2-aminoadamantane-2-carbonitrile by mineral acid or alkali have been unsuccessful. However, treatment of the aminonitrile with benzaldehyde in alkaline solution gives the benzal derivative of the α-aminoamide, readily hydrolysed to the α-aminoamide. Alternatively, benzoylation of the amino group followed by acid hydrolysis gives successively the α-benzamido acid and the α-amino acid. Possible mechanisms for these facilitated hydrolyses are advanced.

Abstract:

Background: N-phthalimide amino acid hydrazide is a class of compounds that have the potential therapeutic use. In general, hydrazinolysis of N-substituted amino acid(s) ester removes the ester group and yields the corresponding hydrazide. However, in case if N-substitution group is phthalimide, phthalimide group is cleaved and not the ester group. The resulted compound, therefore, is amino acid ester rather than Nphthalimide amino acid hydrazide. The above class of compounds, because of susceptibility of phthalimide group to hydrazinolysis, has previously been synthesized by a lengthy three-s

Novel asymmetrically meso-substituted porphyrins bearing amino groups have been synthesized as precursors of cationic photodynamic agents.

Abstract:

In the TiCl4-mediated Mannich reaction, β-amino ketones are obtained with diastereoselectivities of 70-95%. The configuration of the major isomer obtained from benzaldehyde, piperidine, and cyclohexanone [2-(α-piperidinobenzyl)cyclohexanone 1] is shown by X-ray crystallography to be unlike (u, cf. Fig. 1). Thus, the trigonal centers combine to form the C–C bond with relative topicity like (lk, 3). Possible mechanisms of the reaction are briefly discussed.
