据报道由d-葡萄糖合成顺-3-羟基-1-脯氨酸。该方法包括将d-葡萄糖转化为N-苄氧基羰基-γ-链烯基胺,其在5-内-trig-氨基汞化作用下以25%的收率得到带有糖附属物的吡咯烷环骨架。另外,通过硼氢化-氧化,甲磺酰化和分子内S N 2环化作用的N-苄氧基羰基-γ-链烯基胺可以高收率得到吡咯烷环化合物。水解1,2-丙酮化物官能团,NaIO 4裂解,然后将醛氧化成酸,然后进行氢解,得到顺式-3-羟基-1-脯氨酸来自d-葡萄糖的总产率为29%。
A newseries of 6-(hydroxyethyl)penems 2-substituted with amino acid-related sidechains was synthesized. The nature of the amino acyl derivative proved to be crucial both from a synthetic point of view, as beta-lactam ring opening can compete with C-2 nucleophilic substitution, and for antibacterial activity. Primary amino acid amides emerged as the most suitable sidechains for enhancing permeability
