Synthesis and Biological Evaluation of Migrastatin Macrotriazoles

The synthesis of three macrotriazoles that are analogues of migrastatin is reported. The synthesis is based on copper(I)- and ruthenium-catalyzed azide\u2013alkyne cycloaddition reactions. The enantiopure terminal alkyne derivatives were prepared by using the Trost desymmetrization, Brown alkoxyallylation and an efficient Colvin reaction. Biological evaluation of the products revealed a promising efficiency in reducing the ability of MDA-MB-361 cell lines to migrate
