The efficient asymmetric synthesis of the antifungal pyrrolidine alkaloid (+)-preussin (2) was accomplished via the stereoselective reduction of a 5-substituted 3-oxo proline. The oxo proline was prepared from an N-sulfinyl δ-amino β-ketoester, a sulfinimine derived polyfunctionalized chiral building block.
抗真菌的吡咯烷生物碱(+)-普鲁星(2)的有效不对称合成是通过立体选择性还原5-取代的3-氧代脯氨酸来实现的。氧代脯氨酸是由N-亚磺酰基δ-氨基β-酮酸酯(一种亚砜胺衍生的多官能手性结构单元)制得的。
