The oxetane ring has evolved as a useful bioisostere for dimethyl and carbonyl groups for the improvement of physiochemical properties of drug candidates. Herein, we report the generation and utilization of highly unstable 3-oxetanyllithium as a hitherto unexplored nucleophile leveraging flash technology. A range of different electrophiles are suitable reaction partners in this protocol, and we demonstrate the utility of this protocol in late-stage pharmaceutical analogue synthesis.

Abstract
The oxetane ring has evolved as a useful bioisostere for dimethyl and carbonyl groups for the improvement of physiochemical properties of drug candidates. Herein, we report the generation and utilization of highly unstable 3-oxetanyllithium as a hitherto unexplored nucleophile leveraging flash technology. A range of different electrophiles are suitable reaction partners in this protocol, and we demonstrate the utility of this protocol in late-stage pharmaceutical analogue synthesis.File in questo prodotto:
