The efficient synthesis of 4S,5S-2-(N-benzyloxycarbonyl)amino-5,6-dihydroxyhex-2-en-4-olide (4) from D-glucuronolactone is described, the potential of (4) as a divergent intermediate for the synthesis of 2S,4S-4-hydroxy-α-amino acids is illustrated by the conversion of (4) to 2S,4S,5S-dihydroxypipecolic acid and bulgecinine [2S,4S,5R-4-Hydroxy-5-(hydroxymethyl)-proline].
描述了由D-葡萄糖醛酸内酯有效合成4S,5S-2-(N-苄氧基羰基)氨基-5,6-二羟基己基-2-烯-4-醇(4)的潜力,(4)作为发散中间体(4)转化为2S,4S,5S-二羟基哌酸和bulgecinine [2S,4S,5R-4-Hydroxy-5-(羟甲基]脯氨酸]。
