The first one pot protocol for the diastereoselective synthesis of oxazolo[2,3-c]isoquinoline was achieved by a metal-free, benzoic acid catalyzed reaction of 1,2,3,4-tetrahydroisoquinoline or trypoline with aldehydes under mild conditions via C–H, C–O bond functionalization. A new approach for the synthesis of highly substituted 1H-pyrrolo[2,1-c][1,4]oxazine was carried out.
在温和的条件下,通过C的无金属苯甲酸催化的1,2,3,4-四氢异喹啉或Trypoline与醛的非金属选择性合成恶唑并[2,3- c ]异喹啉的非对映选择性的第一个反应方案-H,C-O键功能化。开展了一种新的合成高度取代的1 H-吡咯并[2,1- c ] [1,4]恶嗪的方法。
