THE INFLUENCE OF (ORGANO)METALLICS "METAL-TUNING" ON STEREO- AND REGIO-CHEMICAL CONVERGENCE IN REACTIONS OF ALLYLIC CARBANIONS WITH ALDEHYDES

Article abstract of DOI:10.1016/0022-328X(85)80216-3

Although the reaction of heterosubstituted allylic carbanions (2) with aldehydes generally produces a mixture of the γ- and α-adducts (4 and 3), syn-3 and anti-3 can be prepared either exclusively or predominantly by the proper choice of the organometallic compound added.
