Multicomponent synthesis of novel hybrid PHQ-fatty acids†
Abstract
Multicomponent reactions as methods for green synthesis are important pathways for obtaining pharmacological compounds. In this work, an efficient synthesis of new fatty Hantzsch derivative compounds using a four-component reaction is described. We demonstrate for the first time a fatty acid polyhydroquinoline (hybrid PHQ-fatty acids) synthesis from renewable resources containing C16 and C18 saturated and unsaturated fatty chains, including the ricinoleic acid (12-hydroxy-9-cis-octadecenoic acid), the major constituent of castor oil. The experimental results demonstrate that the best value for charging the sulfamic acid was 20 mol% and that thirty new hybrid PHQ-fatty acids were synthesised in good yields.
