Selective arylthiolane deprotection by singlet oxygen: a promising tool for sensors and prodrugs

Chem Commun (Camb). 2015 Feb 21;51(15):3196-9. doi: 10.1039/c4cc09040c.

Abstract

A routine thioketal protecting group reacts rapidly and selectively with singlet oxygen to reveal ketone products in good (aryl 1,3-dithiolane) to excellent (aryl 1,3-oxathiolane) yields. Arylthiolanes are stable to biologically relevant reactive oxygen species and can be used as a light-activated gating mechanism for activating fluorescent sensors or small molecule prodrugs.
