The present invention relates to a method for the manufacture of dihydroisobenzofurans of formula I; comprising generation a dianion of formula II, reaction of the dianion with a carbonyl compound of formula III and acidification of the reaction mixture to generate a diol of formula IV; followed by ring closure of the diol of formula IV to obtain the dihydroisobenzofuran of formula I.
本发明涉及一种制备式I的二氢异苯并呋喃的方法;包括生成式II的二阴离子,将二阴离子与式III的羰基化合物反应,并酸化反应混合物以生成式IV的二元醇;随后将式IV的二元醇环合以获得式I的二氢异苯并呋喃。
