A number of 3-(2-substituted oxazol-5-yl)indoles have been prepared by aza-Wittig type reaction of iminophosphorane derived from 3-azidoacetyl-1-methylindole with isocyanates and acid chlorides. This methodology has been used also to synthetize five pimprinine analogues.
通过衍生自3-叠氮乙酰基-1-甲基吲哚的亚氨基正膦与异氰酸酯和酰基氯的氮杂维蒂希型反应,制备了许多3-(2-取代的恶唑-5-基)吲哚。该方法也已用于合成五种丙丙宁类似物。
