Participants

Reaction Steps

2-Phenyl-4H-1,3,4-oxadiazine-5(6H)-one (0.30 g) synthesized according to Receuil des Travaux chimiques des Pays Bas, 1929, 48, 417, 3-hydroxy tetrahydrofuran (0.30 g) and triphenyl phosphine (0.89 g) were dissolved in tetrahydrofuran (10 ml). Under ice-cooling, 40% diethyl azodicarboxylate/toluene solution (0.59 g) diluted with tetrahydrofuran (3 ml) was added thereto, followed by stirring overnight at room temperature. The reaction solution was evaporated and purified by Cromatorex NH silica gel chromatography (hexane/ethyl acetate system), to give the title compound (0.15 g, 36%).
