method is reported for the synthesis of 3-(2-aryl-ethylidene)isoindolin-1-ones and 3-(2-arylethylidene)isobenzofuran-1(3H)-ones, proceeding with good to excellent yields and (E:Z) selectivity. This methodology involves the sequential reduction-dehydration reaction of readily obtained 3-(2-oxo-2-arylethyl)isoindolin-1-ones and 3-(2-oxo-2-arylethyl)isobenzofuran-1(3H)-ones followed by a base-catalyzed
报道了一种简单实用的方法来合成3-(2-芳基-亚乙基)异吲哚啉-1-酮和3-(2-芳基-亚乙基)异苯并呋喃-1(3 H)-酮,产率高至优。 (E:Z)选择性。该方法涉及容易获得的3-(2-氧代-2-芳基乙基)异吲哚啉-1-酮和3-(2-氧代-2-芳基乙基)异苯并呋喃-1(3 H)-酮的顺序还原脱水反应。通过在乙腈中与K 2 CO 3进行碱催化的双键异构化来实现。使用该方法已经完成了对AKS-182的简明合成的开发。
