Overview

Randomized trial demonstrates the effectiveness of a novel organocatalyst in synthesizing tetrahydrobenzo[b]pyrans under green conditions, suggesting significant advancements in sustainable chemistry.

Key Points

  • This research aims to develop a hydrazone-based porous organic polymer as an efficient organocatalyst for multicomponent synthesis of tetrahydrobenzo[b]pyrans.
  • Synthesis of NBH-POP via solvothermal condensation technique.
  • Characterization using 13 C CP-MAS NMR, FTIR, PXRD, BET, TGA, FE-SEM, HR-TEM.
  • Evaluation of catalytic performance in one-pot Knoevenagel-Michael cascade reaction.
  • NBH-POP shows excellent yields in the synthesis of tetrahydrobenzo[b]pyrans under mild conditions.
  • Catalyst retains structural integrity and activity over multiple recycling cycles, illustrating its robustness.
  • High density of hydrazone linkages provides numerous active sites for substrate activation.
