  Natural product synthesis from (8aR)- and (8aS)-bicyclofarnesols: synthesis of (+)-wiedendiol A, (+)-norsesterterpene diene ester and (−)-subersic acid

  摘要：

  Both enantiomers (8aR)-7 and (8aS)-7 of bicyclofarnesol were synthesized from the enzymatic resolution products (1R,4aR,8aR)-1,2,3,4,4a,5,6,7,8,8a-decahydro-5,5,8a-trimethyl-2-oxo-trans-naphthalene-1-methanol-2-ethylene acetal (8aR)-5 (98% ee) and acetate of(1S,4aS, 8aS)-1,2,3,4,4a, 5,6,7,8,8a-decahydro-5,5,8a-trimethyl-2-oxo-trans-naphthalene-1-methanol-2-ethylene acetal (8aS)-6 (> 99% ee), respectively. The formal synthesis of (+)-wiedendiol 1 was achieved via a coupling reaction of an ate complex derived from 1,2,4-trimethoxybenzene with allyl bromide (8aS)-8 derived from (8aS)-7. The total synthesis of (+)-norsesterterpene diene ester 2 was achieved, based on the synthesis of (13E,10S)-alpha,beta-unsaturated aldehyde 12, derived from (8aS)-7, followed by the selective construction of the (3E,5E)-diene moiety including a C(2)-stereogenic centre in (+)-2. The total synthesis of (-)-subersic acid 3 was carried out based on a Stille coupling between allyl trifluoroacetate congener 25c, derived from (8aR)-7, corresponding to the diterpene part, and aryl stannane congener 26 in the presence of Pd catalyst and CuI as an additive.

  (−)-Subersic acid (1), a new derivative of p-hydroxybenzoic acid in which the m-position is substituted with a bicyclic diterpenoid, was synthesized from (S)-3-hydroxy-2,2-dimethylcyclohexanone and p-hydroxybenzoic acid. The stereochemistry of this sponge-derived inhibitor of human 15-lipoxygenase was established as (5R,10R)-1. (© Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2003)

  The first synthesis of (−)-spongianolide A (1), a cytotoxic sesterterpenoid, and determination of its absolute structure are described. In this synthesis, a simple and practical method for preparation of enantiomerically pure bicyclic and tricyclic β-ketoesters, and a new Wittig reagent, furanmethylide, were developed.
