Abstract: We report the preparation of enantioenriched secondary alkylcarbastannatranes via a stereoinvertive SN2 reaction of enantioenriched alkyl mesylates and carbastannatranyl anion equivalents. Using this process, enantioenriched secondary alcohols may be converted into highly enantioenriched alkylcarbastannatranes, which… read more here.

Abstract: Dynamic asymmetric induction (DYASIN) of racemic dynamic chiral heterohelicenes afforded their highly enantioenriched forms (up to 96% ep) in quantitative yields. These heterohelicenes were readily converted into semi-static axial-chiral 1,1'-binaphthyl derivatives in a stereospecific manner. read more here.
