of enantiopure 4‐oxy‐substituted 3‐aminopyrrolidines arising from the enantioselective ring‐opening of meso‐3‐pyrroline oxide have been developed as catalysts for the asymmetric, anti‐selective Mannich reaction (see scheme; PMP=p‐methoxyphenyl; PG=protecting group). Very high catalytic activity (down to 0.01 mol % loading) and stereoselectivity have been recorded.
减轻负担!已经开发了由内消旋3-吡咯啉氧化物的对映选择性开环产生的对映纯4-氧取代的3-氨基吡咯烷类,作为不对称,反选择性曼尼希反应的催化剂(见方案; PMP =对甲氧基苯基; PG =保护基)。记录到非常高的催化活性(低至0.01 mol%的负载量)和立体选择性。
