Here, we report a short and efficient synthesis of isoindolin-1-ones. Base-induced cyclization of o-hydroxymethyl-benzamides, which was easily prepared from the corresponding phthalides and amines, led predominantly to N-alkylation in good yield. The reaction proceeded under mild conditions and bromine and nitrile substituents were tolerated. The selectivity is explained by HASB theory.
在这里,我们报告了 isoindolin-1-ones 的简短而有效的合成。邻羟甲基苯甲酰胺的碱诱导环化很容易由相应的邻苯二甲醚和胺制备,主要导致 N-烷基化,收率良好。反应在温和的条件下进行,并且可以耐受溴和腈取代基。HASB 理论解释了选择性。
