Abstract
Scandium triflate catalyzed allylation of a variety of aldehydes and aldimines using polyethylene glycol (PEG) as a recyclable reaction medium proceeds smoothly and affords corresponding homoallylic alcohols and amines in good yields. Furthermore this catalyst catalyzes total regioselective ring opening of terminal 1,2-epoxides to bishomoallylic alcohols in good yields. The PEG-scandium triflate catalyst system can be reused for a number of cycles without significant loss of activity.
