  Cyclopropane-Containing Eicosanoids of Marine Origin. Biomimetic Synthesis of Constanolactones A and B from the Alga Constantinea simplex

  摘要：

  Asymmetric syntheses of 7, a substance isolated from incubation of arachidonic acid with an acetone powder of the coral Plexaura homomalla, and of constanolactones A (9) and B (10), metabolites of the red alga Constantinea simplex, are described. The key step involves stannic chloride-mediated cyclization of the oxirane derived from Sharpless epoxidation of 10-hydroxy-5,8-decadienoates, and is shown to yield a trans disubstituted cyclopropane Linked to a delta-lactone. Both (R) and (S) configurations at C5 of the lactone are produced in the cyclization, the ratio being independent of olefin geometry in the acyclic precursor, Elaboration of the cyclization products via Nozaki-Kishi coupling of the derived aldehydes 26 and 37 with the appropriate (1E,5Z)-1-iodo-1,5-undecadiene led to 7, 9, and 10, thereby establishing the relative configuration of 7 and confirming the absolute configuration of 9 and 10.

• Total Synthesis of Solandelactones A, B, E, and F Exploiting a Tandem Petasis−Claisen Lactonization Strategy

  Solandelactones A, B, E, and F were synthesized using Nozaki-Hiyania-Kishi coupling of iododiene 13 with aldehydes 14 and 99 obtained by oxidation of alcohols 92 and 94. Key steps in the synthesis of 92 and 94 were (i) a Nagao asymmetric acetate aldol reaction of aldehyde 77 with thionothiazolidine 78 to set in place an alcohol that becomes the (7S) lactone center of solandelactones, (ii) a Simmons-Smith cyclopropanation of 80 directed by this alcohol, and (iii) Petasis methylenation of cyclic carbonate 90 in tandem with a Claisen rearrangement that generates the octenalactone portion of solandelactones. Synthesis of solandelactones A, B, E, and F confirmed their gross structure and absolute configuration at C7, 8, 10, and 14 but showed that alcohol configuration at C11 must be reversed in pairs, A/B and E/F, from the previous assignment made to these hydroid metabolites. Thus, solandelactones A and B are correctly represented by 2 and 1, respectively, whereas solandelactones E and F are 6 and 5. A biogenesis of solandelactones is proposed for these C(22) oxylipins that parallels a hypothesis put forward previously to explain the origin of C(20) cyclopropane-containing algal products.
