Recent Developments in Multi-component Synthesis of Lawsone Derivatives.

Background: 2-Hydroxy-1,4-Naphthoquinone (HNQ; Lawsone) is one of the most useful and the simplest naturally occurring naphthoquinones and has stimulated a resurgence of interest in the past decades due to a wide range of pharmacological activities.

Introduction And Methods: This activity has led to the unusually large emphasis being placed on the design of more efficient multi-component reactions (MCRs) in the synthesis of bioactive lawsone derivatives.

Results And Conclusion: This review highlights the recent developments in multi-component synthesis of biologically relevant naphthoquinone linked and fused heterocyclic derivatives carried out from 2015 till now.
