The methods of synthesis of two type of monofluorinated α,β-epoxyphosphonates, fosfomycin analogues, with the vicinal and geminal arrangement of fluorine and phosphorus atoms have been developed. The electrophilic monofluorination of enamine or β-enaminophosphonate using Selectfluor® have been evaluated. The selective bromination of resulting α-fluoro ketone followed by addition of phosphite and cyclization
已经开发了具有氟和磷原子的邻位和双位排列的两种类型的单氟化α,β-环氧膦酸酯,磷霉素类似物的合成方法。烯胺或的电monofluorination β -enaminophosphonate使用的Selectfluor ®进行了评价。选择性溴化所得的α-氟代酮,然后添加亚磷酸酯并环化,首先得到所需的α,β-环氧膦酸酯。的α -氟- β -ketophosphonate已被转换成各种氟化的卤代经由卤化并与硼烷络合物还原。氟代卤代醇的闭环反应产生了环氧乙烷或适当的磷酸盐。产物结构已通过1 H,13 C,19 F和31 P NMR光谱确认。
