1-苄基-4-苯基-1H-1

糖类化合物合成中常用保护基的脱除2008-12-04 17:00一、苄醚类除了极少情况下以外，苄基在寡糖合成中是作为永久性保护基的，最后可以催化氢化脱去。

而在苄基苯环的邻对位附加一些基团可以使其具有一定的选择性。

对氨基苄基类：对三甲基乙酰胺基苄基（PAB），酸稳定，用2，3-二氯-5，6-二氰-1，4-二苯醌氧化除去。

对叠氮基苄基（Azb）和对叠氮基间氯苄基（ClAzb）：氧化断裂，在酸性环境下稳定，转化为氨基正离子后便可通过氧化选择性的离去。

对卤基苄基：与苄基一样稳定，经过钯催化氨化后很容易就被质子酸或路易斯酸除去，后来Wong 引入了纳米钯使得苄基从树脂上选择性的脱下成为可能。

改成卤素取代基，又可以增加此类基团的选择性。

以上所有新的苄基保护基，在寡糖合成中能作为临时保护基，被选择性脱除，它们也已经在固相合成复杂寡糖和和支链糖结构中，作为临时保护基得到应用二、碱不稳定保护基乙酰基(Ac)，苯甲酰基(Bz)和三甲基乙酯(Piv)保护基：作为具有邻基参与基团功能的保护基，被广泛用于寡糖固相合成。

用过量的甲醇钠即可脱去，在很短时间内能定量地得到游离羟基.三甲基乙酯(Piv)作保护基偶联时没有酰基迁移和原酸酯现象，脱保护可以用甲醇钠。

在可溶性聚合物载体上，也有报道用1，5-二氮双环[5.4.0]-十一-5-烯（DBU）或Hünig碱的，还有用胍和盐酸的。

氯乙酰基(CA)：可以在甲氧基乙醇中用硫脲脱去。

苯氧乙酰基：在CPG上合成寡糖时用过量的胍反复处理便可脱去乙酰丙酯(Lev)：作为保护基可以促进a选择性，脱保护用甲醇钠，醋酸缓冲的肼也可以将其选择性脱去。

能和9-芴-甲氧基酰基（Fmoc）在固相合成上联用。

三氯乙氧基酰基(Troc)：可用甲醇钠脱去。

在活化锌相对温和的条件下也可以脱去。

9-芴-甲氧基酰基(Fmoc)：很早就在肽合成里作为氮保护基，最近在寡糖固相合成里也得到了广泛应用，可用20%三乙胺脱去，肼和醋酸的二氯甲烷/甲醇溶液也可以将其脱去，而对保护基乙酰丙酯（Lev）没有影响。

促进剂⼤全促进剂⼤全环氧树脂的固化反应，只有脂肪胺、多数改性胺、部分脂环胺固化剂可于室温进⾏，⾄于芳⾹胺、⼏乎全部酸酐类、咪唑类、三氟化硼胺络合物等，都需在中温或⾼温下反应固化。

即使能室温固化...环氧树脂的固化反应，只有脂肪胺、多数改性胺、部分脂环胺固化剂可于室温进⾏，⾄于芳⾹胺、⼏乎全部酸酐类、咪唑类、三氟化硼胺络合物等，都需在中温或⾼温下反应固化。

即使能室温固化的脂肪胺和低分⼦聚酰胺，当温度低于15℃时固化速度很慢，像低分⼦聚酰胺还基本不固化。

为了加速固化反应，降低固化温度，缩短固化时间，提⾼固化程度，减⼩固化内应⼒，节省能源消耗，必须加⼊固化促进剂。

促进剂主要起催化作⽤，降低固化剂的反应活化能，改变反应机制，⼤多也参加固化反应。

其结果是⼤⼤改善了固化物的强度、韧性、耐热性、耐⽔性等物理⼒学性能。

促进剂有很多类型，如叔胺及其盐、脂肪胺、取代脲、有机胍类、咪唑及其盐、⼄酰丙酮⾦属盐、有机羧酸盐、膦化物及其誖盐、酚类、三氟化硼胺络合物、亚磷酸三苯酯、微胶囊、过氧化物、咪唑啉、钛酸酯、纳⽶⼆氧化钛等，分别适⽤于不同的固化体系。

实际上⼀些胺类、咪唑类、三氟化硼胺络合物等既是固化剂，也⽤作促进剂，只是⽤量较少⽽已。

⼀、叔胺及其盐类叔胺及其盐是⼀类亲核型促进剂，对环氧树脂和固化剂有双重催化作⽤。

主要⽤作酸酐、芳⾹胺、低分⼦聚酰胺等固化剂的促进剂，其促进效果与叔胺分⼦结构中氮原⼦的电⼦云密度和分⼦链⼤⼩有关，电⼦云密度越⼤（碱性越强）、取代基越⼩，促进效果就越好。

从E-51与甲基六氢苯酐（50:50）不同促进剂在150℃下的凝胶时间可以明显看出，苄基⼆甲胺2min、吡啶3min、三甲胺6min、三⼄胺8min、三⼄醇胺10min、N，N-⼆甲基苯胺22min。

需要注意，叔胺类促剂加⼊酸酐后，长期储存时可能出现胀桶现象，其原因是发⽣了化学反应放出⼆氧化碳，并⽣成⿊⾊聚合物，使酸酐出现质变。

①DMP-30中、⾼温反应活性较⼤，促进作⽤明显，⽤量0.5～5份。

化工中间体Chenmical Intermediate2013年第08期20科研开发冯芸齐建（周口市质量技术监督检验测试中心，河南周口466000）摘要：1,4-二氢吡啶衍生物是一类重要的有机化合物，以苯甲醛、乙酰乙酸乙酯和碳酸氢铵为原料一步合成了2,6-二甲基-4-苯基-3,5-二乙氧基羰基-1,4-二氢吡啶。

该方法具有原料易得、产率高、环境友好等优点。

关键词：1,4-二氢吡啶Hantz sch 反应绿色合成中图分类号：O626文献标识码：A文章编号:T1672-8114(2013)08-020-02前言1,4-二氢吡啶衍生物是一类重要的有机化合物，具有很好的生理活性，在生物、医药等方面有广泛应用,临床上不仅用于治疗高血压、心绞痛和动脉粥状硬化等心脑血管疾病[1]，而且用于治疗肠胃疾病及治疗肺动脉高压和癫痫病的辅助药物[2,3]。

该类化合物的合成通常采用Hantzsch 反应，但该合成路线具有反应时间长、产率低等弊端[4]。

近年来不断有文献报道合成该类化合物的新方法和新路线，但仍然存在诸如反应温度要求较高、使用毒性较高的溶剂和昂贵的催化剂、分离难度较大、产率低等缺点，不符合绿色化学发展的要求。

因此，改进其合成方法以及合成新的1,4-二氢吡啶化合物已成为研究者广泛关注的热点之一。

近十年来，不断有新的绿色合成的方法见诸报道。

陈维一等[5]用碳酸氢铵代替浓氨水合成了一系列1，4-二氢吡啶衍生物，缩短了反应时间，提高产率。

屠树江等[6]应用微波辐射技术一步合成4-芳基-1,4-二氢吡啶衍生物，反应时间短,产率优良,后处理方便，无污染。

史达清[7]报道了在氯化三乙基苄基铵(TEBA)催化下在水中一步合成了4-芳基-1,4-二氢吡啶衍生1，4-二氢吡啶衍生物的绿色合成研究物，具有产率高、污染少、环境友好等特点。

蔡小华等[8]以碳酸氢铵、醛和1，3-二羰基化合物为原料，于70℃利用碳酸氢铵受热分解提供Hantzsch 合成反应所需的氨，缩合反应得到1,4-二氢吡啶类化合物。
