An efficient procedure for the synthesis of formylacetic esters

An efficient synthesis of formylacetic esters via ozonolysis of trans-β-hydromuconic esters followed by a solid-supported triphenylphosphine reduction has been developed. In addition, an extension toward formylacetic amides and a one-pot preparation of more stable intermediates which can be used for further transformations are also described.

A convenient synthesis of indole-substituted 2-pyrrolidones and their cyclized derivatives

Condensation between indole, Meldrum's acid, and benzyloxycarbonylacetaldehyde or aminoacetaldehyde derivatives yielded trimolecular adducts 7a-c. The latter were cyclized to indole-substituted 2-pyrrolidones 15a-b or 3-aminopyrrolid-2-ones 18a-b, dependi
