The Hiv Virus Encodes For A Unique Aspartyl Protease That Is Essential For The Production Of Enzymes And Proteins In The Final Stages Of Maturation. Protease Inhibitors Have Been Useful In Combating The Disease. The Inhibitors Incorporate A Variety Of Isosteres Including The Hydroxy-Ethylurea At The Protease Cleavage Site. We Have Shown That The Replacement Of T-Butylurea Moiety By Benzothiazolesulfonamide Provided Inhibitors With Improved Potency And Antiviral Activities. Some Of The Compounds Have Shown Good Oral Bioavailability And Half-Life In Rats. The Synthesis Of Benzothiazole Derivatives Led Us To Explore Other Heterocycles. During The Course Of Our Studies. We Also Developed An Efficient Synthesis Of Benzothiazole-6-Sulfonic Acid Via A Two-Step Procedure Starting From Sulfanilamide. (C) 2003 Elsevier Ltd. All Rights Reserved.

专利号:US-9233943-B2 优先权日:2012-01-10 标题:Process for synthesis of syn azido epdxide and its use as intermediate for the synthesis of amprenavir and saquinavir 发明人:GADAKH SUNITA KHANDERAO; REKULA REDDY SANTHOSH; SUDALAI ARUMUGAM 权利人:COUNCIL SCIENT IND RES 摘要:A novel synthetic route to the syn-azido epoxide of formula 5 includes cobalt-catalyzed hydrolytic kinetic resolution of a racemic mixture of the azido-epoxide. Reaction steps include subjecting an allylic alcohol to epoxidation with mCPBA to obtain a racemic epoxy alcohol; ring opening the epoxy alcohol with azide anion to obtain an anti-azido alcohol, which can then be selectively tosylated at the primary alcohol; treating the tosylate with base to obtain the racemic azido-epoxide; and subjecting the racemic azido-epoxide to cobalt-catalyzed hydrolytic kinetic resolution to obtain the syn-azido epoxide of formula 5. The compound of formula 5 may be used as a common intermediate for the asymmetric synthesis of HIV protease inhibitors, such as Amprenavir, Fosamprenavir, Saquinavir, and formal synthesis of Darunavir and Palinavir.
