A series of hitherto unknown acyclic 5,5-difluoro-5-phosphono-pent-2-en-1-yl-pyrimidines (9a, b, 13a, b), -purines (16a, b) and -(1,2,4)-triazolo-3-carboxamide (19) were successfully synthesized from (E)-1-bromo-5-diethoxyphosphoryl-5,5-difluoro-pent-2-ene in a stereoselective manner. All the synthetized compounds were assayed for antiviral activity against various viruses, but were found to be neither
一系列迄今未知的无环5,5-二氟-5-膦酰基-戊-2-烯-1-基-嘧啶(9a,b,13a,b),-嘌呤(16a,b)和-(1,2由(E)-1-溴-5-二乙氧基磷酰基-5,5-二氟-戊-2-烯以立体选择性方式成功地合成了(4)-三唑并-3-羧酰胺(19)。测定所有合成的化合物对各种病毒的抗病毒活性,但发现它们既没有活性也没有毒性。
