Convenient Synthetic Approach

A convenient synthetic approach to meso-substituted with 2,2’-bipyridine and 1-(pyridin-2-yl)isoquinoline residues calix[4]arenes is reported. This approach involves the reaction of generated in situ 2-lithio-calix[4]arene with 1,2,4-triazine precursor with the following aromatization of the obtained adduct, and the aza-Diels-Alder reaction of the 1,2,4-triazinyl-substituted calix[4]arene with 2,5-norbornadien or in-situ generated 1,2-dehydrobenzene. The UV/fluorescence response of thus obtained meso-pyridyl-substituted calix[4]arenes to metal cations is studied.

Diels Alder Reaction

Synthesis of compound 16, a ring A seco derivative of quassin (1), is described. The overall strategy consists of manipulations within a rigid system established by a Diels–Alder reaction, followed by unfolding of the molecule. The sequence includes a cyclization of a 1,5-bromoketone with Zn and a selective oxidation of one carbonyl group in a tricyclic diketo diester with peracetic acid.
