In topic I： The Chemistry of 1-Methyl-2-phenylcyclopropene The chemistry of cyclopropenes is abundant, and contains many unusual processes, such as ene dimerizations, coupling reactions, rearrangement, and [2+2] cyclizations to release strain energy. 1,2-Disubstituted cyclopropene, 1-methyl-2-phenylcyclopropene (59), was generated from bromo-lithium exchange of 1-bromo-2-phenyl- cyclopropene followed by treatment with methyl iodide. When cyclopropene 59 was treated with thiophenol, cyclopropane 71 and 72 were produced. Compound 59 underwent ene dimerization in the neat state to form the endo-dimer 78 and exo-dimer 79 followed by oxidization with oxygen to give aldehyde 64. It is noteworthy that the endo dimer 78 and 79 could be trapped with thiophenol to give adduct 73, 74 and 75, and that the crossed ene reaction of exo dimer 79 with monomer 59 gave an ene trimer 80 through an exo-transition state. This part is still in distinguishing for compound 76 oxidized to form sulfoxide 81 and sulfone 82. In topic II：The Photoisomerization of 1,3,5-Hexatrienes Photochemistry of alkenes induced trans-cis isomerization reactions and intramolecular cyclizations. For ene dimerization of 1-phenyl-2-trimethylsilylcyclopropene generated four ene dimer. At first dimers 15 and 16 can underwent coupling dimerization to form 1,3,5-hexatriene 17. The other dimers 17 and 18 reacted with oxygen through ring opening and oxidation to yield aldehyde 21. Furthermore, triene 17 proceed photoisomerization to afford photoproducts 18、19&19’ and 24 upon irradiation with UV light (365 nm). In topic III：The Chemistry of 1-Chloro-3-trimethylsilylcyclopropene For simple cross-conjugated methylenecyclopropene (1) can underwent dimerization to provide new conjugated system；The characteristic of terminal alkyne contained the extending of conjugated system and the easy of stacked and coupling advantage. Therefore it had potential applications in chemical and organic photoelectric materials. The key precursor, 1-(2-chloro-3-tirmethylsilylcyclopropyl)prop-2-yn-1-one (14), was prepared via ene reaction、rearrangement、substitution and oxidation。However, the reaction resulted in three products by surprise when 14 reacted with LDA for the formation of exocyclic double bond. As a result, the one of aromatic product is 1,4-diphenylbutane；Besides, compound 14 was treated with LDA follow by different addition reactions to afford adduct 20 和 21.

Abstract:

Nanospheres utilized in targeted drug delivery systems have seen much attention, however it is difficult to detect the nanospheres in an in-vivo test due to their nanoscale in size. This is a crucial step in targeted drug delivery to show the nanosphere being concentrated at the spot of interest. Nanospheres developed by oil in oil (o/o) emulsion technique have the advantage of encapsulating molecules, such as 1,6-Diphenyl-1,3,5-hexatriene (DPH), without damages and chemical alterations. In current study, DPH was encapsulated into a nanosphere as a fluorescing tracer to visualize the nanospheres trafficking in a mouse model of squamous cell carcinoma (SCC). The SCC tumors were established on nude mice. 0.5 ml of a 0.3 mg/ml solution of fluorcescent nanospheres were subcutaneously injected around the tumor. The injections of the drug carrier system were repeated at 2-day intervals till the sacrifice of the tumor-bearing animals on day 10. The tumors were retrieved for frozen and paraffin-embedded histological preparation. Fluorsescent microscopy was used to image the frozen sections, and compared with H&E stained sections. The fluorescence nanoparticles were easily identifiable under fluorescent microscopy, while typical histology images were unable to detect the nanospheres. The data suggest that fluorescent nanoparticles can be used to identify the location or localization of the nanospheres in an in-vivo environment in a simple and straightforward method that aids in characterization of targeted drug delivery.
