Highly Enantioselective Allylation of Ketones: An Efficient Approach to All Stereoisomers of Tertiary Homoallylic Alcohols

Autor: Marcus Brauns, Marian Guder, Jörg Pietruszka, Martin Breugst, Julie Schmauck, Marvin Mantel

Publikováno v: Chemistry (Weinheim an der Bergstrasse, Germany). 23(50)

An optimized protecting group for allylboronates allowed the use of ketones in order to synthesize all isomers of quaternary homoallylic alcohols with high enantioselectivities. All symmetric isomers of the allylboronate were prepared in high yields
