## Several (3S,4S)-and (3S,4R)-statine derivatives have been prepared by attack of nucleophiles on crystalline, epimeric N-BOC-lactams 7a and 76. The key step in the synthesis of the lactams was the TiC/4-catalyzed coupling reactions of acetals derived from (R)-1,3-butanediol with a//y/trimethy/si

New exwnpZes of the cyanation reaction are described, including one that affords the cyanokydrin 8\_, an intermediate for synthesizing pyretkroid insecticides. Also the reaction with acetals derived from S-1,3-butanediol has been examined. \_ Recently we have shown that the Lewis acid catalyzed reac
