Cyclocondensation of aliphaticdiamines with CH2O and H2S (1:3:2 ratio, 0 °C) was carried out to give thiadiazabicyclanes and dithiadiazabicyclanes (1:6:4 ratio), which were previously difficult to synthesize. Symmetric α,ω-bis-1,3,5-dithiazinanes were synthesized at 80 °C by this reaction. The stereochemistry of thiadiazabicyclanes was assigned by 1H and 13C NMR spectroscopy and by theoretical DFT
进行脂肪族二胺与CH 2 O和H 2 S(比例为1:3:2,0°C)的环缩合反应,得到噻二氮杂双环烷和二噻二氮杂双环烷(比例为1:6:4),以前难以合成。通过该反应,在80℃下合成对称的α,ω-bis-1,3,5-二噻嗪酮。噻二氮杂双环烷的立体化学通过1 H和13 C NMR光谱学和理论DFT计算确定,而双-二噻嗪酮的立体化学通过固态X射线衍射研究确定。
