  Cyclopentanones. XII. An Alternative Synthesis of Prostaglandins Involving Catalytic Hydrogenation of 2, 3-Dialkyl-4-Dihydroxy-2-Cyclopentenones

  摘要：

  AbstractA novel approach to Corey's aldehyde is described. A suitable substituted all cis 2, 3‐dialkyl‐l, 4‐cyclopentanediol system is obtained by catalytic reduction of 2, 3‐dialkyl‐4‐hydroxy‐2‐cyclopentenones. Epimerisation to the prostaglandin configuration occurs spontaneously when later on the Horner reaction is carried out.

  Abstract3‐Alkyl‐1,2,4‐cyclopentanetriones can readily be converted to all trans 2,3‐dialkyl‐1,4‐cyclopentanediols. The latter compounds are intermediates for the synthesis of a prostanoid synthon, known as Corey's lactone, when the alkyl substituents contain appropriate functional groups. The conversion of two different sets of side‐chains to readily distinguishable two‐carbon and one‐carbon aldehyde units is described. Extensive 1H‐NMR data are included.
