Hemoglobins were used to catalyze the multicomponent synthesis of indolizines. Satisfactory yields and mild reaction conditions make this method highly useful for practical applications. Furthermore, this study provides a new example of a hemoglobin‐catalyzed organic reaction and is expected to expand the utilization of hemoglobin in organic synthesis.

The Cu-catalyzedthree-component reaction between quinolines, diazo compounds, and alkenes has been established for direct construction of indolizine derivatives via quinolinium ylides. This methodology is distinguished by the use of a commercially inexpensive catalyst and readily available starting materials, wide substrate scope, and operational simplicity.
