The reaction of phosphorus(III) halides with 6-substituted imidazo[2,1-b]thiazoles in the presence of bases proceeds regioselectively and affords 5-phosphinoimidazo[2,1-b]thiazoles, useful synthons for the preparation of various P(III) and P(V) derivatives. 5-Phosphinoimidazo[2,1-b]thiazoles are selectively alkylated at the phosphorus or heterocyclic nitrogen atom, depending on the alkylating agent
在碱的存在下,卤化磷 (III) 与 6-取代的咪唑并 [2,1-b] 噻唑的反应具有区域选择性,并提供 5-膦基咪唑并 [2,1-b] 噻唑,这是制备各种磷的有用合成子(III) 和 P(V) 衍生物。5-膦基咪唑并[2,1-b]噻唑在磷或杂环氮原子处被选择性地烷基化,这取决于烷基化剂。© 2005 Wiley Periodicals, Inc. 杂原子化学 16:648–655, 2005; 在线发表于 Wiley InterScience (www.interscience.wiley.com)。DOI 10.1002/hc.20166
