Synthesis of Non-natural Aza-Iridoids via Ynamides and Molecular Networking-Based Tracing of Their In Planta Bioconversion

J Org Chem. 2022 Jun 3;87(11):7229-7238. doi: 10.1021/acs.joc.2c00445. Epub 2022 May 12.

Abstract

A synthesis of new-to-nature aza-iridoids via ynamides is presented. ZrCl4 proved to be the best acid to perform this transformation. Various ynamides were accommodated, and seco-iridoids could be obtained as well. Aza-iridoids were infiltrated into leaves of Scrophularia Nodosa, an iridoid-producing plant species. High-resolution mass spectrometry coupled to computational metabolomic approaches was employed for the detection of aza-iridoid bioconversion products.
