Abstract

An efficient method has been developed for the preparation of a-aminophosphonates by using zinc di(L-prolinate) as a catalyst under mild reaction conditions. The method has the advantages of high yields, short reaction times, and easy workup conditions. [ABSTRACT FROM AUTHOR]

Abstract

Recently, methodologies that are in accordance with green chemistry principles have been garnering increasing attention. One of the most applied methods in this field is heterogeneous catalysis. In this context, many catalysts have been developed, and there is one remarkable class that has emerged: hybrid materials. Such heterogeneous catalysts are developed from organic and inorganic portions, especially from amino acids and metal salts, which are commonly found in the literature. Herein, we introduce Zn[Pro] 2 and Zn[Gly] 2 as heterogeneous catalysts in thio-Michael reactions via the implementation of two methods: via (1) a magnetic stirrer and (2) via an ultrasound device; the latter method resulted in minimally increased reaction yields in all cases.
