organocatalyst (2R)‐ or (2S)‐[diphenyl(trimethylsilyloxy)methyl]pyrrolidine as organocatalyst. The regioselective ring opening of aziridines and epoxides enabled us to achieve the highly efficient asymmetric synthesis of the antibiotic edeine D fragment 3‐hydroxy‐4,5‐diaminopenatanoic acid, an intermediate for the formal synthesis of non‐proteinogenic amino acid (−)‐galantinic acid, and for potent
合成有价值的手性(氮丙啶-2-基)环氧乙烷基-3- carbaldehydes轴承从(氮丙啶-2-基)acrylaldehydes与H的立体选择性环氧化反应制备三个连续的官能团,包括氮丙啶,环氧化物,和醛2 ö 2使用有机催化剂( 2 R)‐或(2 S)-[二苯基(三甲基甲硅烷基氧基)甲基]吡咯烷作为有机催化剂。氮丙啶和环氧化物的区域选择性开环使我们能够实现抗生素乙二胺D片段3-羟基-4,5-二氨基戊二酸的高效不对称合成,这是非蛋白原氨基酸(-)-正式合成的中间体没食子酸,强效抗真菌药(+)-普鲁斯汀以及医学上重要的构架3-羟基-2-羟甲基吡咯烷。
