A practical method for the deoxygenation of α-hydroxyl carbonyl compounds under mild reaction conditions is reported here. The use of cheap and easy-to-handle Na2S·9H2O as the reductant in the presence of PPh3 and N-chlorosuccinimide (NCS) enables the selective dehydroxylation of α-hydroxyl carbonyl compounds, including ketones, esters, amides, imides and nitrile groups. The synthetic utility is demonstrated
本文报道了一种在温和反应条件下使 α-羟基羰基化合物脱氧的实用方法。在 PPh 3和N-氯代琥珀酰亚胺 (NCS) 存在下,使用廉价且易于处理的 Na 2 S·9H 2 O 作为还原剂,可以对 α-羟基羰基化合物(包括酮、酯、酰胺)进行选择性脱羟基、酰亚胺和腈基团。合成效用通过生物活性分子和复杂天然产物的后期脱氧来证明。
