摘要
Two diastereomeric epoxides 4a and 4b corresponding to the C-25-C-36 fragment of arenicolides A and B were synthesized in a stereoselective manner involving the Pd(0)-catalyzed stereospecific methoxy substitution reaction of epoxy unsaturated ester 6 with B(OMe)(3) as the key step. Comparison of the H-1 NMR spectra of the synthetic compounds with that of arenicolide A revealed that the configuration of the epoxide in arenicolides A and B is 30R and 31R.
