We report in this paper a new simple one-step procedure for the synthesis of a wide series of 1-silylallylic amines substituted at position 2 from the readily available3 precursor NJ-bis (trimethylsily1) propargylamine (1) by means of a silylcupration followed by in situ reaction with electrophiles, according to Scheme I. One of the most important aspects of the reaction in Scheme I turns out to be the inversion of regioselectivity in the addition of the reagents ...
