Application of Sharpless asymmetric dihydroxylation to thienyl- and benzothienyl acrylates and crotonates
摘要:
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.
