Abstract

Pumiliotoxins and their congeners are a class of compounds isolated from the skin of some frogs from the Dendrobatidae, Mantellidae, Bufonidae, e Myobatrachidae families, possessing interesting pharmacologic activities (cardiotonic activity in low concentrations). Because of the big number of compounds among these toxins (about 100), synthetic methodologies that provide the preparation of these compounds (as well as analogues) in great amounts and in a fast and efficient way using common intermediates, are very important for application in chemical-biology. This project aims the synthesis of these compounds, more specific of the dehydrodemethylpumiliotoxins, from a,b-unsatutated diazoketones with Z geometry. (AU)
