Reaction of α-Aminoacetals with 2-Methylresorcinol

摘要

The main method of synthesis of calix[4-resor-cinols is the condensation of resorcinol and its derivatives with aliphatic or aromatic aldehydes [1-3]. We have recently extended synthetic opportunities of this method by involvement into the reaction with resorcinol of phosphorylated acetals to obtain calix[4] resorcinols with phosphorylalkyl substituents at the lower rim of the molecule [4].
