Abstract

Ynoate esters are ideal reagents for one-pot reactions due to their ability to undergo multiple addition reactions in one flask. Ethyl propiolate undergoes a heteroconjugate addition reaction with aromatic thiol nucleophiles, producing an enoate which is then oxidized by m-CPBA and is able to undergo a Diels–Alder reaction with cyclopentadiene. The work presents the optimization of a three-step heteroconjugate addition-oxidation-Diels–Alder reaction to yield cyclic compounds favoring endo stereochemistry, which may be used in further synthesis of biologically active compounds such as (+)-Methyl-5-epi-Shikimate or Deipeptyl-IV-Peptidase inhibitor.
