Biphenyl-bridged ϵ-sultams with excellent enantioselectivities (up to 97 % ee) were synthesized through organocatalyticMannichreactions of seven-membered cyclic N-sulfonylimines with unactivated methyl alkyl ketones. Unactivated ketones containing a smaller alkyl substituent or hydroxyacetone substrates will gave major syn selective Mannich products at the methylene group.
通过七元环 N-磺酰亚胺与未活化的甲基烷基酮的有机催化曼尼希反应合成了具有优异对映选择性(高达 97% ee )的联苯桥联 ε-磺内酰胺。含有较小烷基取代基或羟基丙酮底物的未活化酮将在亚甲基上产生主要的顺式选择性曼尼希产物。
