Abstract
We report herein an enantioselective acyl transfer protocol via electrophile activation. The reaction cascade
sequence encompasses dinuclear zinc-catalyzed asymmetric Michael addition, intramolecular cyclization, and
retro-Claisen reaction, which leads to a step- and atom-economic approach to a variety of protected cyclic tertiary
α-hydroxyketones in good yields with excellent enantioselectivities (24 examples, 56%-82% yield, 1.5-13 dr and
79%-96% ee). Besides, the large-scale synthesis and further transformation of the products demonstrate the
effectiveness of this method for organic synthesis.
Keywords: Acyl transfer, retro-Claisen reaction, zinc catalyst, nitroolefins, -hydroxy-1-indanones
