一种直接构建两个相连叔碳-叔碳键的方法
技术领域
[0001] 本发明涉及一种化学合成方法,具体地说,是一种直接构建两个相连叔碳-叔碳键 的方法。
【背景技术】
[0002] 碳-碳键是有机化合物最主要的组成部分,所以发展各种各样的快速构建碳碳键 的方法,历来都是化学工作者关注的热点话题。值得一提的是,2010年的诺贝尔化学奖,正 是颁发给了三位在"钯催化的偶联反应直接构建碳-碳键"的领域做出巨大贡献的科学家。 但是,目前发展的偶联反应往往是构建两个位阻比较小的碳原子之间的化学键;对于构建 位阻比较大的两个叔碳原子之间的化学键,一直是化学家亟待攻克的难题。因为位阻太大, 两个叔碳原子接近会比较困难,另外这类反应中往往会伴随消除反应。目前,构建叔碳-叔 碳键通常使用的方法是四取代烯烃的加成反应,但是四取代烯烃的合成限制了该方法的运 用。
【发明内容】
[0003] 本发明的目的是提供一种直接构建叔碳-叔碳键的方法,即通过炔丙基叔醇碳酸 酯和叔碳亲核试剂,在钯催化剂、双膦配体、碱的作用下,在有机溶剂中加热反应,一步直接 构建叔碳-叔碳键的方法。
[0004] 本发明是采用以下具体技术方案来实现的:
[0005] 本发明公开了一种直接构建两个相连叔碳-叔碳键的方法,在钯催化剂和双膦配 体作用下,炔丙基叔醇碳酸酯和叔碳亲核试剂在碱的存在和在有机溶剂中加热反应下,生 成叔碳-叔碳键化合物,产物中的炔某官能闭讲一步转化为其它某闭,皮应式如下:
[0006]
[0007] 其中R1为烷基或者芳基;妒、沪为烷基;所述的炔丙基叔醇碳酸酯是外消底物或光 学活性底物;R4,R 5为酯基,羰基,氰基;R6中包含多种官能团,所述的官能团是联烯、炔基、烯 基、芳基或者烷基中的一种或几种。
[0008] 作为进一步地改进,本发明的具体操作步骤如下:
[0009] 1 )、反应管加入碱,在油栗抽真空状态下,用电烘枪烘烤反应管,随后充入氮气,如 此反复三次;反应管冷至室温后,在氮气气氛下依次投入钯催化剂、双膦配体、炔丙基叔醇 碳酸酯、叔碳亲核试剂、有机溶剂,将反应管置于油浴中加热并搅拌;
[0010] 2)、待步骤1)反应完全后,将反应管从油浴中提出,自然回复室温,慢慢加入IOmL 体积比为10%的稀盐酸淬灭反应;所述的稀盐酸是市售浓盐酸稀释十倍;
[0011] 3)、待步骤2)完成后,用乙醚萃取,有机相依次用水和饱和实验水洗,无水硫酸钠 干燥,过滤,浓缩,快速柱层析得最终产物。
[0012] 作为进一步地改进,本发明所述的钯催化剂为醋酸钯,氯化钯,三(二亚苄基丙酮) 二钯,二(二亚苄基丙酮)一钯中的任意一种。
[0013] 作为进一步地改进,本发明所述的催化剂是醋酸钯。
[0014] 作为进一步地改进,本发明所述的双膦配体为1,Γ-双(二苯基膦)二茂铁,1,2_双 (二苯基膦)乙烷,1,3-双(二苯基膦)丙烷,1,4-双(二苯基膦)丁烷,2,2 双_(二苯膦基)-1,1 联蔡中的任意一种。
[0015] 作为进一步地改进,本发明所述双膦配体为1,1'_双(二苯基膦)二茂铁。
[0016] 作为进一步地改进,本发明所述的碱为碳酸钾,碳酸铯,磷酸钾,氢氧化钾,氢氧化 钠中的任意一种。
[0017] 作为进一步地改进,本发明所述的碱是碳酸钾或者碳酸铯。
[0018] 作为进一步地改进,本发明所述有机溶剂为二甲亚砜,Ν,Ν-二甲基甲酰胺,Ν,Ν-二 甲基乙酰胺,四氢呋喃,乙腈中的任意一种。
[0019] 作为进一步地改进,本发明所述的有机溶剂为二甲亚砜。
[0020] 本发明具有以下优点:(1)原料简单易得,制备方便;(2)反应温和,操作简单;(3) 底物普适性广,官能团兼容性好;(4)产物易分离纯化;(5)原料炔丙基叔醇碳酸酯的手心中 心可以非常高效地转移到产物中去。
