An efficient, environmentally friendly and one-pot route to new 9-aryl/9-arylethynyl-2,3,4,9-tetrahydro-1H-xanthen-1-one derivatives from inexpensive starting materials has been developed. This method proceeded by a domino nucleophilic-substitution/intramolecular cyclization/dehydration sequence of propargylic amines/diaryl amines and 1,3-cyclohexanediones under the promotion of FeCl3, which involved
已经开发了一种从廉价的起始原料制备新的9-芳基/ 9-芳基乙炔基-2,3,4,9-四氢-1 H-黄嘌呤-1-酮衍生物的有效,环境友好的途径。在FeCl 3的促进下,炔丙基胺/二芳基胺和1,3-环己二酮的多米诺亲核取代/分子内环化/脱水序列进行了该方法,该过程涉及形成两个新的σ(C–C和C–O )在一个单一操作中就可以以68%至95%的产率构建新颖的四氢氧杂蒽骨架。
