Synthesis of amino acid derivatives of hydrazones and oximes of spirodihydropyranochromen-2-ones
摘要:
Sulfur-and nitrogen-containing derivatives of spirodihydropyranochromen-2-ones at the exocyclic oxygen atom have been synthesized. Modification of the oximes and hydrazones of the spiro-substituted pyranocoumarins with N-substituted amino acids were carried out using activated ester and symmetrical anhydride methods.
