The -Wittig rearrangement of chiral (Z)-allylic benzyl ethers provides 94-97percent of asymmetric transfer (enantiospecificity), along with 90-96percent of erythro-selectivity.Its synthetic potential is illustrated through the stereocontrolled synthe

(Chemical Equation Presented) One step beyond: The first single-step stereospecific transition-metal-catalyzed conversion of allylic electrophiles into monoalkyl diazenes is described. This synthesis of allylic monoalkyl diazenes offers a new strategy for asymmetric synthesis by the reduction of optically active substrates or the use of chiral catalyst systems. Sensitive substrates are reduced in a highly selective manner. Ar = 2-NO2C 6H2.

Using 1,2-dicyclohexyl-1,2-ethanediol as chiral auxiliary, the enantiomerically pure Z-pentenylboronate 9c was obtained.Its addition to benzaldehyde proceeded with complete transfer of chirality to give the syn-E-homoallyl alcohol 11.The ability of the re
