摘 要:以4-(4-氨基苯基)-3-吗啉酮(2)与2-[(2S)-2-环氧乙烷基甲基]-1H-异吲哚-1,3-(2H)-二酮(3)为原料,经开环反应后以双(三氯甲基)碳酸酯羰基化,然后以甲胺脱保护,最后与5-氯-2-噻吩甲酰氯经酰胺化合成得利伐沙班,总收率为76.8%,其结构经1H NMR与MS确证。

Abstract:Rivaroxaban was synthesized by a four-step reaction: at first the epoxy-opening reaction of 4-(4-aminophenyl)morpholin-3-one(2)with 2-[(2S)-oxiran-2-ylmethyl]-1H-isoindole-1,3(2H)-dione(3); then the cyclization reaction of the epoxy-opening reaction product with bis(trichloromethyl)carbonate to form oxazolidin-2-one; then oxazolidin-2-one was deprotected using methylamine; at last, amidation of the deprotected oxazolidin-2-one with 5-chlorothiophene-2-carbonyl chloride to give the final product. The structure of rivaroxaban was proved using 1H NMR and MS spectra, and the total yield of the target product was 76.8%.
