Cationic triazinium heterocycles by intramolecular NN bond formation
摘要:
Tricyclic heterocycles with a cationic triazinium core were prepared by an intramolecular N-N bond forming reaction of an azine oxime precursor. The azine oxime substrates were prepared by SNAr N-arylation of 2-formylpyrroles followed by oxime formation of the formyl moiety. The synthesis was demonstrated with five different azines and several functional groups. (C) 2014 Elsevier Ltd. All rights reserved.

The first manganese(I)‐catalyzed C−H allylations with ample scope were achieved by carboxylate assistance. The highly selective C−H/C−O functionalizations proved viable with densely substituted allyl carbonates, and the organometallic C−H allylation strategy set the stage for expedient late‐stage diversification with excellent levels of positional selectivity.
通过羧酸盐的辅助作用,第一个锰(I)催化的CH烯丙基化作用范围很大。事实证明,高选择性的C / H / C-O功能化可用于稠密取代的碳酸烯丙酯,有机金属的C-H烯丙基化策略可为后期分散化提供有利的条件,并具有出色的位置选择性。

A novel and efficient C–H activation approach for the direct 3,3-difluoroallylation of 2-pyridones and indoles is herein reported using a manganese(I) complex as the catalyst. A broad range of substrates with diverse functional groups were tolerated. Moreover, late-stage C–H functionalization of bioactive molecules was achieved in good yield.
