A one-pot sequence of organocatalytic transformations delivers heteroarylmethylene-substituted pyrrolidines with high stereo- and enantioselectivity. A Mannich coupling of N-heteroarylalkyne aldehydes with aldimine and an original metal-free hydroamination of the resulting adducts are the key transformations of the process delivering highly functionalized molecules with high potential for synthetic applications.
一种单锅序列的有机催化转化反应以高立体选择性和对映选择性合成了杂环亚甲基取代的吡咯烷。N-杂环芳烃炔醛与醛胺的曼尼奇偶联反应以及对所得加合物进行的原位无金属氢氨化反应是该过程的关键转化,能够产生具有高度功能化的分子,具有良好的合成应用潜力。
