High Regiocontrol in the Zinc-Mediated Crotylation of Aldehydes and Ketones: A Straightforward and Facile Approach to Linear Homoallylic Alcohols in DMPU
α-regioselectivity of carbonyl crotylation is a long-standing problem in the realm of C–C bond formation reactions. We demonstrate that zinc-mediatedcrotylation of aldehydes and ketones can afford α-linear homoallylicalcohols exclusively to provide a simple solution for this problem. In this context, we describe a method for the α-regioselective crotylation of aldehydes and ketones by using an easily available
