英文摘要
The following new results have been obtained :1.New organozinc reagents and their Lewis-acid complexes were prepared by reaction of organozinc with Cu (I) slats. It is found that these new reagents were highly effective for the stereo-and regioselective 1,3-chirality transfer reactions of a vinyl group.2.It is found that the above reagents can be prepared from both organolithium and Grignard reagents. Addition of LiCl stabilize the reagents.3.It is found that the reaction of g-mesylor gamma-tosyloxy-alpha, beta-enoates can be transformed into alpha-vinyl-beta, gamma-enoates in a highly regio-and stereoselective manner.4.Methods for potentially useful isomertization of gamma, delta-imino-alpha, beta-enoates by treatment with Pd (Ph_3) _4 at room temperature have been developed.5.Four L-Leu-PSI [ (E) CH=CH ] L-Leu, L-Leu- PSI [ (E) CH=CH ] D-Leu, L-Val-PSI [ (E) CH=CH ] L-Leu, and L-Val-PSI [ (E) CH=CH ] D-Leu isosteres have been synthsized. Incorporation of these dipeptide isosteres into polypeptides can be done in a highly effective manner. These isosteric peptides showed very high bombesin antagonist activity.
