专利号:WO-2013138200-A1 优先权日:2012-03-13 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.

专利号:EP-0671928-B1 优先权日:1992-09-24 标题 :Synthesis of n-substituted oligomers 发明人:ZUCKERMANN RONALD N; KERR JANICE M; KENT STEPHEN BRIAN HENRY; MOOS WALTER H; SIMON REYNA J; GOFF DANE A 权利人:CHIRON CORP 摘要:Poly N-substituted Glycines (poly NSGs), wherein the substituents bear purine or pyrimidine bases (R<9>) every second glycine: In addition, a solid phase method for the synthesis of N-substituted oligomers of more general structures is disclosed.The poly NSGs obtainable by this method can have a wide variety of side-chain substituents. Each N-substituted glycine monomer is assembled from two 'sub-monomers' directly on the solid support. Each cycle of monomer addition consists of two steps: (1) acylation of a secondary amine bound to the support with an acylating agent comprising a leaving group capable of nucleophilic displacement by -NH2, such as a haloacetic acid, and (2) introduction of the side-chain by nucleophilic displacement of the leaving group, such as halogen (as a resin-bound alpha -haloacetamide) with a sufficient amount of a second sub-monomer comprising an -NH2 group, such as a primary amine, alkoxyamine, semicarbazide, acyl hydrazide, carbazate or the like. Repetition of the two step cycle of acylation and displacement gives the desired oligomers. The efficient synthesis of a wide variety of oligomeric NSGs using the automated synthesis technology of the present method makes these oligomers attractive candidates for the generation and rapid screening of diverse peptidomimetic libraries. The oligomers of the invention, such as N-substituted glycines (i.e. poly NSGs) disclosed here provide a new class of peptide-like compounds not found in nature, but which are synthetically accessible and have been shown to possess significant biological activity and proteolytic stability.
