| Abstract: | Lithiation of 3-methoxymethyl quinuclidine N-oxide occurs regioselectively to generate the 2-lithio 3-methoxymethyl derivative which can be trapped out with non-enolisable electrophiles to give 2,3-disubstituted quinuclidine N-oxide derivatives in good yield. |
| Keywords: | Amine oxide Lithiation Quinuclidine |
