Palladium-Catalyzed γ-Selective Arylation of Zincated Boc-Allylamines
摘要:
The regio- and diastereoselective arylation of Boc-protected allylamines was performed via a one-pot lithiation/transmetalation to zinc/cross-coupling sequence, through an appropriate choice of a phosphine ligand. A variety of γ-arylated products were obtained in moderate to good yield, and the products could be directly transformed into valuable γ-arylamines and β-aryl aldehydes.

A highly chemoselective and simple method for the deprotection of N-allylic amines usingDDQ has been developed. The use of DDQ in dichloromethane–water provides a mild and efficient one-step deallylation of a wide variety of orthogonally protected tertiary amine derivatives.
