Asymmetric allylation and vinylation of aldehydes with allyl halides and vinyl halides have been achieved using the chromium(II)-oxazoline catalyst. The catalyst promotes the highly efficient enantioselective Nozaki–Hiyama-Kishi (NHK) allylation of aldehydes using allyl bromide, producing the corresponding homoallylic alcohols in good yields (up to 84%) and a high level of enantioselectivity (up to 98% ee). Meanwhile, the NHK vinylation of aldehydes produce desired allylic alcohols in satisfactory yields (up to 88%) and a high level of enantioselectivity (up to 97% ee). We developed a reliable and milder protocol for preparing chiral homoallylic and allylic alcohols.

A series of diazepinomicin derivatives were synthesized and evaluated in vitro for their growth inhibitory activity against the human carcinoma cell lines. The results indicated the anticancer selectivity of this kind of compounds. Based on the results, preliminary structure-activity relationships were discussed.

Monosubstituted 5-, 6-, and 8-methoxy-3,4-dihydro-2,3-pentamethylenequinazolones (1-3) have been synthesized by the condensation of monosubstituted methoxyanthranilic acids with caprolactam.Demethylation with hydrobromic acid gave the corresponding hydroxy compounds .When the 6- and 8-methoxy- and 6- and 8-hydroxy-3,4-dihydro-2,3-pentamethylenequinazolones (2, 3, 5, and 6) were reduced with zinc in hydrochloric acid, the corresponding quinazoline derivatives (7-10) were obtained.The melting points of the bases and their hydrochlorides are given.Some features of their UV, mass, and PMR spectra are reported.
