The syntheses of 1and 7-hydroxypyrrolizidin-3-ones are described via asymmetric catalytic hydrogenation or diastereoselective reduction of ketones as key steps. 2,7-Disubstituted pyrrolizidin-3-ones are also prepared. The second chiral center is created using stereoselective electrophilic amination or hydroxylation reactions.
通过不对称催化氢化或酮的非对映选择性还原作为关键步骤描述了 1 和 7-羟基吡咯里西啶-3-酮的合成。还制备了 2,7-二取代的 pyrrolizidin-3-ones。第二个手性中心是使用立体选择性亲电胺化或羟基化反应产生的。
