, p. 903 - 910 (2007/10/02)
α-Phenoxy- (4) and α-methoxycrotylboronates (8) were obtained from the α-chlorocrotylboronates 1.Addition of the phenoxy compound to aldehydes gave the homoallyl alcohols 5/6 as Z/E mixtures; addition of the methoxy compound led to essentially pure Z-enol ethers 9.Enantiomerically enriched (ca. 90percent e.e.) 8 was used in reactions with chiral aldehydes to ensure the formation of the new stereogenic centers under reagent control of diastereoselectivity. - Key Words: Reagent control of stereoselectivity / Z-Enol ether, formation of / Allylboronates, addition to aldehydes
