The organocatalytic enantioselective trifluoromethylthiolation of oxindoles employing N-(trifluoromethylthio)phthalimide as a stable, easy to handle CF3S-source has been developed. Optically active products with a quaternary stereogenic center bearing a CF3S-group are obtained in good yields and with good to excellent enantioselectivities.
已经开发了使用N-(三氟甲硫基)邻苯二甲酰亚胺作为稳定,易于处理的CF3S源的恶唑的有机催化对映选择性三氟甲硫基化。获得具有CF 3 S-基团的四元立体异构中心的旋光产物,其收率高且对映选择性良好。
