Condensation Reaction of Phenols with 1,5-Pentanedial for Synthesis of Noria-like Ladder-cyclic Oligomer by Dynamic Covalent Chemistry Mechanism
Condensation reaction of 2-methylresorcinol and pyrogallol with 1,5-pentanedial [CH2(CH2CHO)(2)] in the presence of concentrated HCl in ethanol at 80 degrees C for 48 h proceeded according to a dynamic covalent chemistry (DCC) mechanism to afford the noria-like ladder-cyclic oligomers noria(MR) and noria(PY), respectively.
