Chem. Commun., 2014, Advance Article
DOI: 10.1039/C4CC03766A, CommunicationGuy Rouquet, David C. Blakemore, Steven V. Ley
The first regioselective ortho-lithiation at the 4-position of simple pyridine derivatives containing a 3-oxetane unit has been achieved using n-butyllithium as base. Electrophilic quenching of the resulting lithio species provides a rapid access to a broad range of new functionalized pyridine oxetane building blocks.
