α- and α'-lithiation-electrophile trapping of N-thiopivaloyl and N-tert-butoxythiocarbonyl α-substituted azetidines: rationalization of the regiodivergence using NMR and computation
(1)H NMR and computational analyses provide insight into the regiodivergent (α- and α'-) lithiation-electrophile trapping of N-thiopivaloyl- and N-(tert-butoxythiocarbonyl)-α-alkylazetidines. The magnitudes of the rotation barriers in these azetidines indicate that rotamer interconversions do n...
