In this paper is described a synthesis of enantiomerically enriched, configurationally stable organozinc reagents by catalytic enantioselective carbozincation of a vinylboronic ester. This process furnishes enantiomerically enriched α-borylzinc intermediates that are shown to undergo stereospecific reactions, producing enantioenriched secondary boronic ester products. The properties of the intermediate α-borylzinc reagent are probed and the synthetic utility of the products is demonstrated by application to the synthesis of (-)-aphanorphine and (-)-enterolactone.
Stereochemical proof for front side deuteride attack via σ-sulfurane in the reductive desulfinylation of sulfoxides with lithium aluminum deuteride

Stereochemical results obtained from the concomitant reduction and desulfinylation of 1-phenyl-2-pyridyl-2(p-tolysulfinyl)- and 1,2-diphenyl-2-phenylsulfinyl ethanols with lithium aluminum deuteride reveal that the reactions proceed stereospecifically via
