Addition of Metalated 3‐Alkyl‐Substituted Alkoxyallenes to Imines: Preparation of Tetrasubstituted 2,5‐Dihydropyrroles, Pyrrolidin‐3‐ones, and Pyrroles

Metalated 3‐alkyl‐substituted methoxyallenes were either generated by lithiation of the corresponding methoxyallenes or, according to a procedure of Brandsma, from 3‐alkyl‐substituted propargyl methyl ethers. Additions of these axially chiral intermediates to various imines afforded the expected all...
