               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




               INTRODUCTION
               Acyl transfer presents an omnipresent and efficient chemoselective ligation process in biological systems ,
                                                                                                        [1]
               which has attracted extensive attention in the chemical community in recent years . In order to circumvent
                                                                                    [2]
