Abstract
Sterically shielded 1,2,4-trioxolanes prepared by Griesbaum co-ozonolysis have been utilized as chemical sensors of ferrous iron in several recently described chemical probes of labile iron. Here we report optimized conditions for co-ozonolysis that proceed efficiently and with high diastereoselectivity across an expanded range of substrates, and should enable a new generation of labile iron probes with altered reaction kinetics and physicochemical properties.
Improved, low temperature conditions for Griesbaum co-ozonolysis enables the preparation of structurally diverse 1,2,4-trioxolane-based sensors of ferrous iron for caging of reporters and therapeutic payloads.![]()
