Regioselective and stereoselective oxidation of steroidal palladium π-allyl complexes to allylic alcohols
Abstract
Steroidal palladium π-allyl complexes are oxidised regiospecifically and with high stereoselectivity to allylic alcohols by 3-chloroperbenzoic acid in light petroleum containing pyridine, the hydroxy-group being delivered preferentially to the same diastereotopic face of the π-allyl system as that originally occupied by palladium.
