A review on DBU-mediated organic transformations

Green Chemistry Letters and Reviews, Journal Year: 2022, Volume and Issue: 15(3), P. 765 - 795

Published: July 3, 2022

1,8-Diazabicyclo[5.4.0]undec-7-ene (DBU) has received a significant importance in organic synthesis during recent years because of its interesting ability to catalyze reaction sufficiently at mild conditions. DBU can work as catalyst under simple conditions inducing the operational simplicity experimental procedures by reducing side products and waste. The notable advantages these cases include less expensive which is commercially readily available, easy handle, most importantly recoverable. been explored for several practical methodologies highly useful wide variety materials. selectivity (chemo-, regio-, stereo-) reactions impressive applicable modern chemical transformations. possesses enhanced basic properties high mechanical well thermal stability. In years, large number transformations have carried out using catalyst. successfully employed conduct including usual modifications, cyclizations, eliminations, esterifications, condensation reactions, multicomponent etc. fact, last few decades, tremendous interest sparked various promoted publications appeared literature. Since catalyzed recently proven be important we review this article protocols
