PROCEDURE

实验过程

601 mg of tetronic acid and 1.01 g of the epoxide of example 1 are reacted analogously to example 6 with 180 mg of sodium hydride (80%) and 747 mg of borontrifluoride-diethyletherate in tetrahydrofurane. Usual work up yields white crystalls of the title compound. m.p. 111°-114° C. (dichloromethane/ether)
