Controlled Synthesis of Novel Dibenzene-1,2-diol Mannich Bases

Abstract

The synthesis of a number of novel dibenzene-1,2-diol Mannich bases can be achieved in good yields by the condensation of 2-methoxyphenol, formaldehyde and secondary diamines. The newly developed synthetic method uti lizes 2-methoxyphenol instead of benzene-1,2-diol providing a useful tool for greater control over reaction products.
