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

24 January, 2015 - 13:17

Chem. Commun., 2015, Advance Article
DOI: 10.1039/C4CC09040C, CommunicationBrian M. Lamb, Carlos F. Barbas III
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.
