Reaction Steps
A quantity of 4.3 grams of 4-oximino-5-methyl-1,3-oxathiolane was caused to react with 3.5 ml of methylisocyanate in the presence of dibutyltin diacetate in ethyl ether and worked up as described in Example I to give 6 grams of crude 4-(methylcarbamoyloximino)-5-methyl-1,3-oxathiolane. Recrystallization from isopropyl ether/ethyl acetate afforded pure syn isomer, mp 70.0°-71.5°; structure confirmed by spectral analysis.
