A 1,3-Lithium Shift of Propargylic/Allenylic Lithium and the Subsequent Transmetalation Coupling Reaction with Aryl Halides

摘要

Selective synthesis has been a formidable challenge in organic synthesis,especially controlled highly selective synthesis beginning from the same starting materials.Herein,we report a novel clean 1,3-lithium shift reaction of propargylic/allenylic lithium (Scheme 1).
