Copper catalyzed synthesis of spiro-indolofurobenzopyrans: Tandem reactions of diazoamides and O-propargyl salicylaldehydes

Org. Biomol. Chem., 2019, Accepted Manuscript DOI: 10.1039/C9OB01275C, CommunicationSengodagounder Muthusamy, Ammasi Prabu, E Suresh An atom-economical synthesis of spiro-indolofurobenzopyrans has been developed from diazoamides and O-propargyl salicylaldehydes in the presence of copper(I) thiophene-2-carboxylate in a diastereoselective manner. This methodology involves the carbonyl ylide intermediates... The content of this RSS Feed (c) The Royal Society of Chemistry
