Stereoselective Syntheses of cis- and trans-Hexahydrocyclopenta[c]pyran-3(1H)-ones
摘要:
A new access to cis- and trans-hexahydrocyclopenta[c]pyran-3(1H)-ones (1 and 2) has been accomplished stereoselectively through 4-step and 5-step routes, respectively, starting from 2-(hydroxymethyl)cyclopentanone (3).

A general and efficient method for the synthesis of oxazolidin‐2‐ones and imidazolidin‐2‐ones directly from 1,3‐diols and 3‐amino alcohols has been developed using the same reagent combination of iodobenzenedichloride (PhICl2) and sodium azide (NaN3).

Fluoroolefin dipeptide isosteres were synthesized applying the Peterson reaction as a novel method for fluoroolefination. The dipeptide isosteres were elaborated to provide the conformationally constrained analogs (1-(R), 1-(S) and 2-(R), 2-(S)) of the Suc-Ala-Gly-Pro-Phe-pNA tetrapeptide, a synthetic substate of cyclophilin.

A simplified bicyclicscaffold inspired by the antifungal natural product sordarin was designed and synthesized which maintains the carboxylic acid/aldehyde (or nitrile) pharmacophore. Docking studies with the target for sordarin, the fungal protein eukaryotic elongation factor 2 (eEF2), suggested that the novel scaffolds may bind productively. A densely functionalized chiral cyclopentadiene was constructed
