3-Amino-3-deoxy-2,4,5,6-tetra-O-methyl-D-altronic acid hydrochloride was the key intermediate in the preparation of poly[(2S,3R)-2-methoxy-3-(D-erythro-trimethoxypropyl)propanamide], a chiral nylon 3 analog. We now describe an alternative synthetic route to this amino acid and the unexpected reactivity of some of its 3-deoxy derivatives. Attempts to open the 3-azido-3-deoxy-tri-O-methyl (or O-benzyl)-D-altrono-1
3-氨基-3-脱氧-2,4,5,6-四-O-甲基-D-丙二酸盐酸盐是制备聚[(2 S,3 R)-2-甲氧基-3]的关键中间体-(D-赤型-三甲氧基丙基)丙酰胺],手性尼龙3类似物。现在,我们描述了该氨基酸的替代合成路线及其某些3-脱氧衍生物的出乎意料的反应性。尝试打开3-叠氮基-3-脱氧-三-O-甲基(或O-苄基)-D -altrono-1,5-内酯中间体得到产物的混合物,主要是α,β-不饱和羰基化合物。
