A-Oxygenated crotyltitanium

SCHEME 1 Diastereoselectivity for addition of an a-oxygenated crotyltitanium to aldehydes. [Pg.55]

These methodological studies served to demonstrate that reactions of an a-oxygenated crotyltitanium reagent and aldehyde lead to anft-homoallylic alcohol with a Z-O-enecarbamate group in a one-step sequence. We could take advantage of this functionality to give access either to the natural product or to synthetic analogues. [Pg.58]
