Abstract2‐Isopropyl‐6‐phenyl‐ and 2,6‐diisopropyl‐pyridiniums with bulky 1‐substituents show temperature‐variable NMR spectra which are interpreted in terms of restricted rotation. 2‐Isopropyl‐4,6‐diphenylpyrylium can be deprotonated at the isopropyl group to give an anhydro base which forms new pyryliums with electrophiles.

By utilizing amino allenes, aldehydes, and aryl iodides as readily available building blocks, a simple and modular synthesis of multisubstituted pyridines with flexible control over the substitution pattern has been achieved. The method employs a two-step procedure involving the preparation of "skipped" allenyl imines and a subsequent palladium-catalyzed cyclization.
