developed through an iterative analog library approach, of analogs of the highly selective M1 allosteric agonist TBPB by deletion of the distal basic piperidine nitrogen by the formation of amides, sulfonamides and ureas. Despite the large change in basicity and topology, M1 selectivity was maintained.

A novelmethod for the synthesis of 1,2‐dihydro‐5‐arylnaphtho[2,1‐c][2,7]naphthyridinederivatives via a three‐component reaction of aromatic aldehyde, naphthalen‐2‐amine, and N‐substituted piperidin‐4‐one derivatives is described using 5 mol % iodine as catalyst. The features of this new procedure are mild reaction condition, high yield, operational simplicity, and uses available reactants. J. Heterocyclic
