A facile and one-pot synthesis of 2-benzoxepines, from Baylis–Hillman adducts that is, alkyl 3-aryl-3-hydroxy-2-methylenepropanoates, via treatment with HCHO in the presence of concd H2SO4, involving tandem construction of C–O and C–C bonds via Prins-type and Friedel–Crafts reactions, is described.
的2-benzoxepines一种简便和一锅法合成,从的Baylis-希尔曼加合物即,烷基3-芳基-3-羟基-2- methylenepropanoates,经由处理用HCHO在concd H的存在2 SO 4,涉及串联结构描述了通过Prins型反应和Friedel-Crafts反应的C–O和C–C键。
