Abstract
A method was developed for the synthesis of the first representative of the previously unreported quinuclidine derivatives with four geminal substituents in the α-positions with respect to nitrogen, viz., 2,2,6,6-tetramethylquinuclidine, from triacetonamine. Two variants were studied for building up the chain from two CH2 links in the γ-position of triacetonamine using the Reformatskii and Knoevenagel reactions.
