A stereoselective and efficient preparation of a thiophene containing intermediate 2 from ethyl 3-thienyl propenoate 4 as the core of new possible HIV protease inhibitors is described. The chiral intermediate has been successfully used for the preparation of the analog I of the potent HIV inhibitor nelfinavir. (C) 2004 Elsevier Ltd. All rights reserved.

Optimized conditions for the catalytic asymmetric dihydroxylation have been applied to thiophene and benzothiophene containing acrylates and crotonates to afford the corresponding diols in good overall yields and good to excellent enantiomeric excess. The products obtained were revealed to be useful intermediates in peptidomimetic synthesis. (c) 2006 Elsevier Ltd. All rights reserved.
