## Abstract Concave pyridines 1 were used to catalyze the addition of primary and secondary alcohols to ketenes 4, and the kinetic data of these catalyses were determined. In inter‐ and intramolecular competitions the use of 1e–g led to improved selectivities for the acylation of primary alcohols i

## Abstract Compounds 2–6 were synthesized by starting from the pyridine‐bridged calix[6]arenes 1. Most of these derivatives exist in a concave conformation like their parent compounds 1, but in some cases the conformational behavior is different. Relative basicities of 1–6 and of the open‐chain mo
