Cyclization of thiosemicarbazide with methyl 3-chloro-2-oxo-3-phenylpropionate in MeCN results in 5-hydroxy-2-imino-5-methoxycarbonyl-6-phenylperhydro-1,3,4-thiadiazine. The structure of the product has been confirmed using spectral (IR,1H,13C,13C1H} NMR) methods and chemical transformations.
在 MeCN 中,氨基硫脲与 3-氯-2-氧代-3-苯基丙酸甲酯的环化产生 5-羟基-2-亚氨基-5-甲氧羰基-6-苯基全氢-1,3,4-噻二嗪。产物的结构已使用光谱(IR、1H、13C、13C1H} NMR)方法和化学转化证实。
