“…Over the past few years, many improvements have been made in the synthesis of BZDs with respect to reaction efficiency, purity, eco-friendly process, ambient reaction conditions. 48,49 Several reviews have been published 28,[50][51][52] on the synthesis of BZDs but they cannot encapsulate the latest research work done on this moiety. Singh et al 50 presented synthetic approaches for the synthesis of 1,5-BZDs from 2013 to 2018.…”
