First controlled asymmetric dihydroxylation of thiophene acrylates
摘要:
The AD of thiophene acrylates afforded the corresponding diols with high ees and good overall fields. The low reactivity of the olefins has been enhanced with the use of a modified AD-mix formulation. by adding Lip to 2 mol% of the chiral catalyst. without effect on the reactive thiophene ring.
