Cross-coupling reactions of various organocopper reagents with u-(mesyloxy)ailyls~lanes have been evaluated for stereoselectlve P,P-dlsubstltuted vinylsilane synthesis $2' displacements with RMgBdCuCN(cat ) reagents proceeded In high yields (84+94%) and E-selectlvltles (10 1 -+ 38 1) in THF at -78ยฐC
The ester-allylsilanes ( 5) and ( 6) and the acid-allylsilane (7) react stereoselectively with m-CPBA; the major product from ( 5) and ( 7) was the y-lactone (4), whereas (6) failed to undergo lactonisation, the major product in this case was the P,wpoxy-silane (12).
