Highly stereoselective one-step synthesis of 5-aryl- and 5-(2-styrenyl)-4,5-trans-epoxy-2(E)-pentenols employing an arsonium salt
摘要:
5-Aryl- and 5-(2-styrenyl)-4,5-trans-epoxy-2E-penten-l-ols were conveniently synthesized by a one-step reaction of aldehydes with arsonium salt 2b under mild conditions (rt, KF.Al2O3, phase transfer).
