Controlling factors on the stereochemistry of palladium(II)-catalyzed cyclization of 1'-alkyl-4'-chloro-2'-alkenyl 2-alkynoates
摘要:
Beta,gamma-Disubstituted alpha-(Z)-(chloromethylene)-gamma-butyrolactone derivatives have been prepared highly diastereoselectively via a Pd(II)-catalyzed cyclization of 1'-alkyl-4'-chloro-2'-alkenyl 2-alkynoates. Rationales for the stereochemical results of this reaction are proposed.
