Abstract:

In the last decades the multicomponent reactions have been shown to be an important way to prepare high functionalized compounds within high atom-, energy- and step- economy. One of these compounds are the propargylamines, which are important chiral tools in organic synthesis especially in the pharmaceutical industry. This class of compounds are important building blocks for the preparation of complex amino derivatives and bioactive substances. An important known strategy for the synthesis of this class of compounds consists in the 1,2-addition reaction of non-functionalized acetylenic organometallics to a C-N double bond, usually of imines, enamines, nitrones and iminium salts. In this study, we payed attention to develop a three-component one-step coupling, using alkynols, benzylamine and aldehydes to prepare benzylamine propargyl alcohols.
