Lessing, Timo published the artcileActivation-free one-pot alkynylation-cyclization synthesis of 2-substituted 4-azaindoles and indoles, Application In Synthesis of 39856-58-1, the publication is Chemistry of Heterocyclic Compounds (New York, NY, United States) (2018), 54(3), 334-338, database is CAplus.
2-Substituted 4-azaindoles and indoles were rapidly and efficiently prepared in an activation-free Pd-catalyzed alkynylation-cyclization sequence starting from 3-amino-2-bromopyridine or o-bromoaniline and terminal alkynes in a one-pot fashion.
