that bear versatile functional groups with quaternary stereogenic centers have been prepared with very high enantioselectivity from tertiaryboronicesters (see scheme; Cb=N,N‐diisopropylcarbamoyl, pin=pinacolato). The preparation of allylboronic esters bearing contiguous quaternary and tertiary stereogenic centers, and applications to natural product synthesis are also reported.
