Brönsted acid-catalyzed cascade synthesis of densely substituted benzofurans from easily available salicyl alcohols and biomass-derived furans has been developed. The disclosed sequence includes the intermediate formation of 2-(2-hydroxybenzyl)furans that quickly rearrange into functionalized benzofurans. The established protocol was applied for the total synthesis of sugikurojinol B. The Brönsted
抽象的 已经开发了布朗斯台德酸催化的级联反应,该反应由易于获得的水杨醇和生物质衍生的呋喃进行稠合取代的苯并呋喃的级联反应。公开的序列包括2-(2-羟基苄基)呋喃的中间体形成,其快速重排为官能化的苯并呋喃。已建立的方案适用于sugikurojinol B的全合成。 已经开发了布朗斯台德酸催化的级联反应,该反应由易于获得的水杨醇和生物质衍生的呋喃进行稠合取代的苯并呋喃的级联反应。公开的序列包括2-(2-羟基苄基)呋喃的中间体形成,其快速重排为官能化的苯并呋喃。已建立的方案适用于sugikurojinol B的全合成。
