The traceless Petasis borono-Mannich reaction of enals, sulfonylhydrazines, and allylboronates catalyzed by chiral biphenols results in an asymmetric reductive transposition of the in situ

A Direct Synthesis of Allenes by a Traceless Petasis Reaction Mar 27, 2012 Asymmetric Traceless Petasis Borono‐Mannich Reactions of The traceless Petasis borono‐Mannich reaction of enals, sulfonylhydrazines, and allylboronates, catalyzed by chiral biphenols, results in an asymmetric reductive transposition of the in situ generated allylic diazene. Acyclic 1,4‐diene products bearing either alkyl‐ or aryl‐substituted benzylic stereocenters are afforded in excellent
