Stereoselective and diversity-oriented synthesis of trisubstituted allylic alcohols and amines
Schmidt, Yvonne,Breit, Bernhard
, p. 11789 - 11796 (2011/11/06)
Stereoselective and diversity-oriented synthesis of trisubstituted olefins was achieved by using ortho-diphenylphosphanyl benzoate (o-DPPB) as a directing group for allylic substitution. The starting point of this methodology was a set of α-methylene alde
