Fluorine-containing nitrogen mustards attached to hydrocinnamic acid, phenylpyruvic acid and D,L-phenylalanine as carrier groups have been synthesized. The N-(2-chloroethyl)-N-(2′-fluoroethyl)amines are obtained by alkylation of the sodium salts of N-(benzyloxycarbonyl)amines with 2-fluoroethyl p-toluenesulfonate or 2-bromofluorethane, removal of the benzyloxycarbonyl group, followed by hydroxyethylation
已经合成了与氢肉桂酸,苯基丙酮酸和D,L-苯丙氨酸作为载体基团连接的含氟氮芥。N-(2-氯乙基)-N-(2'-氟乙基)胺是通过将N-(苄氧羰基)胺的钠盐与2-氟乙基对甲苯磺酸盐或2-溴氟乙烷烷基化,除去苄氧羰基基团而获得的,然后进行羟乙基化和氯化。通过在合适的溶剂中将双(2-对甲苯磺酰氧基乙基)胺与氟化钾一起加热来获得双(2-氟乙基)胺。通过这些反应,甲基·甲基··················································································-氨基氢肉桂酸酯被转化为氯氟芥末XIX和双氟芥末XX。从苯胺开始,上述反应与Vilsmeier-Haack反应一起提供了苯甲醛芥子VII和VIII。这些被转化为相应的氮杂内酯。氮杂内酯的两步水解得到苯基丙酮酸的氯氟芥末IXA和双氟芥末IXB。用锌和酸还原a内酯,然后水解,
