Popis: | The first total synthesis of (+)-murolic acid is accomplished in 17 steps from ester 9 in 14.8% overall yield. The key steps involve asymmetric dihydroxylation, orthoester Johnson-Claisen rearrangement and -methylenation using Stiles reagent. A beneficial late stage -epimerization reverted a stereodivergent relay to a stereoconvergent completion of an efficient synthesis of (+)-murolic acid. |
