5 ) 2 ( 1 ). The product obtained on hydrolysis of 1 with concentrated hydrochloric acid is stable only in acid solution and behaves as a hydrate or a polymer of CH 2 OH·CH N + H 3 ·CHO Cl − . It affords a crystalline semicarbazone hydrochloride ( 2 ), 2,4-dinitrophenylhydrazonehydrochloride ( 3 ), and dithioacetal oxalate ( 4 ). Other acyl and alkyl derivatives have been prepared directly from compound
摘要用氢化铝锂还原2-氨基-3,3-二乙氧基丙酸乙酯可得到缩醛CH 2 OH·CHNH 2·CH(OC 2 H 5)2(1)。用浓盐酸水解1得到的产物仅在酸性溶液中稳定,并表现为水合物或CH 2 OH·CH N + H 3·CHO Cl-的聚合物。得到结晶的半卡巴zone盐酸盐(2),2,4-二硝基苯hydr盐酸盐(3)和二硫缩醛草酸盐(4)。其他酰基和烷基衍生物已直接由化合物1制备。仅在溶液中鉴定出的醛CH 2 OH.CH(NHCOCH 3).CHO应该在某些含有氨基糖的多糖进行Smith降解后形成。二乙缩醛12及其O-甲基衍生物15、2,4-二硝基苯基hydr 13,制备该醛的乙撑二硫缩醛14。巯基分解后,还从卵清蛋白糖肽的史密斯降解产物中分离了衍生物14。
