  4. Abstract:
  5. An efficient and one-pot procedure is described for the synthesis of a variety of derivatives of 1,2-dihydrobenzo[f]chromen-3-ones and 3,4-dihydrochromen-2-ones under solvent-free conditions via a pseudo-four-component domino reaction of acetic anhydride, aryl aldehydes, glycine-based dithiocarbamates, and phenols/naphthols in the presence of l-proline and H4[Si(W3O10)4].xH2O as green catalysts. All products were made under the green strategy for the synthesis of corresponding products with excellent yields (up to 94%) and diastereoselectivity. © 2021 Taylor & Francis Group, LLC
