Abstract: There remain challenges for effectively synthesizing heterocycles containingboth piperidine and pyridine rings, mainly due to the inefficient syntheticprocess mostly requiring long reaction times. This paper reports a simple andefficient method

An efficient synthetic route to the potent and selective ErbB VEGF receptor inhibitor, BMS-690514 (1) is described. Strategic modifications in both approach and procedure addressed several issues, which led to a safe, efficient, and economical process for the preparation of multi-kilogram quantities of 1. The convergent route involves alkylation of a suitably protected (3R,4R)-4-aminopiperidin-3-ol with the triethyl(alkyl)ammonium salt of a functionalized pyrrolotriazine 3a followed by deprotection to provide 1 as the crystalline free base.

First total synthesis of AI-77-B (1), a gastroprotective substance from Bacillus pumilus AI-77, was achieved in a stereoselective and convergent manner. In this synthesis, the dihydroisocoumarin part 2 was constructed in one step through 1,2-addition of the benzylic anion 17b to Boc-L-leucinal 7b. The hydroxy amino acid 4 was elaborated from (R)-glutamic acid in a highly stereoselective manner. Condensation of 2·HCl and 4, intramolecular Pinner reaction, followed by mild hydrolysis afforded AI-77-B (1).
