摘要：

An efficient, one-pot synthetic approach to precursors of some new aminochromene/xanthene annulated heterocycles via a tetrabutylammonium hydrogen sulfate-mediated intramolecular domino Knoevenagel-hetero-Diels-Alder reaction is described. The method is general and efficient. The stereochemistry of the product was confirmed by various NMR experiments and single-crystal x-ray diffraction data. Supplemental materials are available for this article. Go to the publisher's online edition of Synthetic Communications (R) to view the free supplemental file.
