trans-3-Hydroxy-l-proline 1, trans-3-hydroxy-l-prolinol 2, cis-3-hydroxy-d-proline 3, and cis-3-hydroxy-d-prolinol 4 have been prepared in enantiomerically pure form with chirospecific manner. Key intermediates, 2-amino-3-hydroxy-4-pentenoate 9 and 17, were obtained from d-glucono-δ-lactone and l-gulonic acid γ-lactone via a simultaneous dealkoxyhalogenation.
反式-3-羟基-L-脯氨酸1,反式-3-羟基-L-脯氨2,顺式-3-羟基d脯氨酸3,和顺式-3-羟基d脯氨醇4已经在对映体纯制备以手性特异性的形式形成。关键的中间体2-氨基-3-羟基-4-戊烯酸酯9和17是通过同时脱烷氧基卤化反应从d-葡萄糖酸-δ-内酯和1-gulonic酸γ-内酯获得的。
