A catalytic enantioselective synthesis of dihydrofurans has been developed. 1,3-Dicarbonyl derivatives react with (E)-β,β-bromonitrostyrenes in the presence of a chiral bifunctional thiourea catalyst providing mild and efficient access to diverse polysubstituted dihydrofurans in good yields and enantioselectivities.
已经开发了二氢呋喃的催化对映选择性合成。1,3-二羰基衍生物在手性双官能硫脲催化剂的存在下与(E)-β,β-溴硝基苯乙烯反应,可提供温和而有效的收率,并以良好的收率和对映选择性接近各种多取代的二氢呋喃。
