标 题 :Green chemistry synthesis of the malaria drug amodiaquine and analogs thereof
发明人：FORTUNAK JOSEPH MARIAN; KULKARNI AMOL ANANT; KING CHRISTOPHER
权利人:UNIV HOWARD
摘要:Methods are provided for a green chemistry one-pot synthesis of amodiaquine and amodiaquine analogs. The methods have a lower environmental impact, lower investment cost, reduced amounts of byproducts and impurities, and a shorter synthesis time, compared to current conventional synthesis methods. The methods reduce the total number of steps in the synthesis from four to five down to two, thereby simplifying production; and allow a reduced number of solvents and reagents to be used in production, thereby reducing the waste generated in the synthesis. The methods can reduce the waste to about 3-5 kilograms of waste generated per kilogram of product produced; and surprisingly improve the overall yield from 60-65% to greater than 90% as compared to the current conventional synthesis methods for amodiaquine and its analogs.
