  Heterocyclic Analogs of Prostaglandins: I. Synthesis of 3-Alkyl(Aralkyl)-2,5-dihydrofuran-2-ones as Synthons for 11-Deoxy-10-oxaprostanoids

  摘要：

  3-Acyl(arylmethyleneacyl)tetronic acids were synthesized. Selective hydrogenation of the carbonyl group in the acyl fragment and reduction of the conjugated double bond afforded in high yield the corresponding 3-alkyl(aralkyl) derivatives possessing either natural or modified prostaglandin alpha-chain. Reduction of the conjugated double bond in vinylogous 3-alkyl(aralkyl)tetronic acid amides with sodium cyanotrihydridoborate gave a mixture of stereoisomeric beta-amino lactones which underwent retro-Michael elimination of the amine residue, leading to 3-alkyl(aralkyl)-2,5-dihydrofuran-2-ones. The latter can be regarded as synthons for 11-deoxy-10-oxaprostanoids.
