Spirocentric Compounds and Polymers Thereof

The present invention is directed to novel functionalized spirocentric compounds and polymers thereof that produce hyper-rigid cross-linked membranes.

A 'Classical' Approach to the Synthesis of Perloline

An approach to the synthesis of perloline by the reaction of (2-bromophenyl)(3',4'-dimethoxyphenyl)amine with a suitably 4-substituted 2-oxo-1,2-dihydropyridine-3-carboxylic acid was unsuccessful due to the inability to form the amide bond.The diphenylamine was efficiently synthesized from the nitrone of dimethoxybenzylidene-2-bromoaniline via the oxaziridine, the thermal rearrangement of which was investigated.Conjugate additions of a diphenylamine dianion to unsaturated esters are reported.
