北京大学化学生物学与生物技术学院杨震课题组利用可见光催化形式[2+2]/retro-Mannich反应构建cyclohepta[b]indole结构(图)
杨震 可见光催化 retro-Mannich反应 cyclohepta[b]indole结构
2021/4/12
近日,我院杨震课题组在《德国应用化学》发表通讯论文,报道了可见光催化形式[2+2]/retro-Mannich反应构建cyclohepta[b]indole结构的研究工作。全碳季碳手性中心普遍存在于复杂天然产物和功能分子,具有重要的结构和功能意义。立体选择性构筑高空间位阻的全碳季碳、甚至连续季碳是有机合成的重点和难点。C-3位为全碳季碳的cyclohepta[b]indole结构,广泛存在于复杂活...
