Pd-catalyzed Cross-Coupling of α-(Acyloxy)-tri-n-butylstannanes with Alkenyl, Aryl, and Heteroaryl Electrophiles
摘要:
Racemic and scalemic alpha-(acyloxy)-tri-n-butylstannanes undergo Pd-catalyzed cross-couplings with alkenyl/aryl/heteroaryl iodides, bromides, and triflates in moderate to good yields in THF at 45 degrees C. Simple aryl iodides and unprotected aza-arenes, two classes of electrophiles that typically react sluggishly, are also good substrates. Cross-couplings proceed with retention of configuration at the alkenyl and stannyl-substituted stereocenters.
