Procedure
A quantity of 3 ml of allyl isocyanate was caused to react with 3 grams of 4-oximino-5-methyl-1,3-oxathiolane dissolved in 50 ml of ether containing 2 drops of triethylamine over a period of 20 hours at room temperature. Conventional workup and recrystallization from isopropyl ether afforded 3 grams of product, mp 66.0°-67.5°, structure confirmed by spectral analysis.
