Triphenylphosphine-Mediated Synthesis of Methyl 2-Aroyloxypropenoates from 2-Aroyl-2-methoxycarbonyloxiranes
摘要:
A new synthesis of several 2-aroyloxypropenoic acid methyl esters 5 by the reaction of 2-aroyl-2-methoxycarbonyloxiranes 2 with triphenylphosphine in tetrahydrofuran has been described.
One-Pot Preparation of 1-Acyl-1-methoxycarbonyloxiranes and 1-Acyl-1-cyanooxiranes from Methyl 3-Hydroxy-2-methylenealkanoates or 3-Aryl-3-hydroxy-2-methylenepropanenitriles
Treatment of Baylis–Hillman adducts with iodosobenzene (PhIO) in the presence of a catalytic amount of KBr in water at room temperature afforded the corresponding acyloxiranes in good yields.

The reaction of sodium hypochlorite with methyl 3-hydroxy-2methylenealkanoates or 3-aryl-3-hydroxy-2-methylenepropanenitriles, dispersed on silica gel, in acetonitrile leads to oxidation of the alcohol function and epoxidation of the methylene group to give 2,2-disubstituted oxiranes in good yield.
