The enantioselective formal synthesis of the polyketide marine natural product (−)-clavosolide A is presented. The construction of the β-C-glycoside subunit is highlighted by a one-pot oxocarbenium cation formation/reduction sequence. Yamaguchi dimerization afforded the diolide aglycon in 18 steps (longest linear sequence).

The present invention relates to the technical field of organic chemical engineering, and in particular to a key intermediate for synthesizing prostaglandin compounds and a preparation method therefor. When applied to the synthesis of prostaglandin compounds, the process flow is simplified, the yield and product purity are improved, the production costs are reduced, and the industrial application is easy.
Concise, scalable and enantioselective total synthesis of prostaglandins
Prostaglandins are among the most important natural isolates owing to their broad range of bioactivities and unique structures. However, current methods for the synthesis of prostaglandins suffer from low yields and lengthy steps. Here, we report a practicability-oriented synthetic strategy for the enantioselective and divergent synthesis of prostaglandins. In this approach, the multiply substituted

see text] The totalsynthesis of the marine diolide (-)-clavosolide A has been achieved in 17 steps (longest linear sequence) from commercially available crotonaldehyde exploiting the Petasis-Ferrier union/rearrangement tactic to construct the requisite aglycon monomer. A one-pot esterification/lactonization employing the Yamaguchi protocol, followed by bis-glycosidation, furnished (-)-clavosolide A
