A convenient route to substituted 2H[1]benzopyrans is described in which trialkylaluminium compounds are added to coumarins or chromones and the resultant Z-2-(3-hydroxy-1-propenyl)phenols are converted by thermal cyclization in the presence of silica gel to 2H[l]benzopyrans.
描述了一种取代2 H [1]苯并吡喃的简便方法,其中将三烷基铝化合物添加到香豆素或色酮中,并在二氧化硅存在下通过热环化反应将生成的Z -2-(3-羟基-1-丙烯基)苯酚转化凝胶至2 H [1]苯并吡喃。
