The synthesis of a number of stable acyloxymethyl carbonochloridates 7 has been accomplished in four steps from chloromethyl carbonochloridate 3. Each step has been optimized with propanoyloxymethyl carbonochloridate 7c as a model compound (64% overall yield). Diethyl ether-boron trifluoride catalyzes the conversion of carbonothioate 6cc to the carbonochloridate 7c by chlorination with sulfuryl chloride. Acylation of a few compounds containing hydroxy or amino groups by 7c is described.
已通过四步反应从氯甲基碳酰氯3合成了一系列稳定的乙酰氧甲基碳酰氯化合物7。以丙酰氧甲基碳酰氯7c作为模型化合物,对每一步反应进行了优化(总产率为64%)。二乙醚-三氟化硼催化硫代碳酸酯6cc通过硫酰氯氯化转化为碳酰氯7c。介绍了7c对含有羟基或氨基的少数化合物的酰化反应。
