General description

1,8-二氮杂双环[5.4.0]十一碳-7-烯是一种双环氨基碱。在有机化学中，它是非亲核、空间位阻叔胺碱。据报道，其在Baylis-Hillman反应中表现优于胺催化剂。在温和条件下，其可促进酚类、吲哚类、苯并咪唑类与碳酸二甲酯的甲基化反应。
默克生命科学致力于为您提供更环保的替代产品，以符合“绿色化学的12项原则”的一项或多项原则要求。该产品为增强型，提高了催化效率。点击此处了解更多详情。

Application

1,8-二氮杂双环[5.4.0]十一碳-7-烯的羟基与二氧化碳发生可逆反应，可作为纤维素溶解和活化的催化剂。溶解的纤维素体系可由纤维素混合酯生成。
1,8-二氮杂双环[5.4.0]十一碳-7-烯（DBU）可：
  • 用作羧酸与二甲基酯化反应的催化剂
  • 用于多卡霉素和CC-1065类似物的合成
  • 用作aza-Michael加成反应和Knoevenagel缩合反应的催化剂
  • 用作卤代Diels–Alder加合物脱卤反应的碱，所得的活化2,4-二烯酮经过区域和空间定向Michael加成，反应采用Yamamoto′s试剂(CH3Cu · BF3)
  • 用于一种新型的喜树碱ABCD环系合成
