摘要: The Diels–Alder reactions of 1-aryl-2-methylene-3-buten-1-ols, readily available from chloroprene and aryl ketones, with olefinic dienophiles subsequent electrocyclic the cycloadducts offer a new method [6.5] annelation to benzene ring. By this way, tetrahydrofluorene skeletons bearing functional groups can be prepared. Stereochemical aspect sequence is also discussed.
