Abstract

Conjugate or Michael addition to vinyl-substituted aromatic N-heterocycles has been a useful synthetic method for the synthesis of functionalized heterocyclic compounds. A wide variety of heterocycles and nucleophiles undergo this chemistry. Recent work in this area has utilized transition-metal catalysts and some asymmetric synthesis has been accomplished. An overview of this chemistry is presented in this account.
