Yang, Yu-Jie; Ji, Yuanyuan; Qi, Liangliang; Wang, Guanjun; Hui, Xin-Ping published the artcile< Asymmetric Synthesis of Cyclopenta[3,4]pyrroloindolones via N-Heterocyclic Carbene-Catalyzed Michael/Aldol/Lactamization Cascade Reaction>, COA of Formula: C9H7BrO, the main research area is heterocyclic carbene catalyst asym Michael aldol lactamization cascade reaction; asym Michael aldol lactamization cascade reaction enal indole enone; functionalized cyclopentapyrroloindolone stereoselective preparation.
The N-heterocyclic carbene-catalyzed asym. Michael/aldol/lactamization cascade reaction of enals and indole-derived enones for the synthesis of functionalized cyclopenta[3,4]pyrroloindolones with four consecutive stereogenic centers, e.g. I, has been achieved. The products were obtained in good yield with high diastereoselectivity and excellent enantioselectivity.
Organic Letters published new progress about Aldol addition catalysts, stereoselective. 3893-18-3 belongs to class bromides-buliding-blocks, and the molecular formula is C9H7BrO, COA of Formula: C9H7BrO.
