Multi-enzymatic cascade processes for alkaloids synthesis

Abstract

Pyrrolizidine, indolizidine and quinolizidine alkaloids are natural products found in plants, insects and amphibians. Due the vast number of biological activities, these compounds became targets for development of new drugs, and their asymmetric synthesis is a recurrent challenge. Herein, we propose an unprecedented multi-enzymatic cascade reactions involving transaminases, imino reductases, followed by a spontaneous intramolecular Aza-Michael reaction, in order to produce enantiomerically pure pyrrolizidine, indolizidine and quinolizidine alkaloids scaffolds, starting from ±,²-unsaturated keto esters. Another part of this project we aim to study the activity of a new monoamine oxidase (MAO) from the fungus Neopestalotiopsis sp, for further uses of this enzyme to synthetize and resolute piperidine and pyrrolidine alkaloids and other valuable cyclic amines.
