Enzymatic kinetic resolution of 1,1-dioxo-2,3-dihydro-1H-1λ6-thiophen-3-ol via temporary derivatisation
摘要:
Following the thio-conjugate addition of (+/-)-9, its enantiomers were extremely efficiently discriminated using Novozym 435 (R). The thio-differentiating unit may then be removed either under reductive conditions, using Raney nickel, or following an oxidation-elimination sequence. In this manner enantioenriched derivatives of 1,1-dioxo-2,3-dihydro-1H-1 lambda(6)-thiophen-3-ol 9 may be accessed. (c) 2006 Elsevier Ltd. All rights reserved.

Design and synthesis of nonpeptidal bis-tetrahydrofuran ligands based upon the X-ray crystal structure of the HIV-1 protease-inhibitor complex 1 led to replacement of two amide bonds and a 10 pi-aromatic system of Ro 31-8959 class of HIV proteaseinhibitors. Detailed structure-activity studies have now established that the position of ring oxygens, ring size, and stereochemistry are all crucial to
