Abstract

Two methyl 5-(2-chloropyridin-3-yl)pentanoates were prepared by condensation of 1,3-bis(silyloxy)-1,3-butadienes with 2-chloropyridine-3-carboxylic acid chloride. The permethylation of the products resulted in two completely different products, depending on the substitution pattern of the 1,3,5-tricarbonyl moiety.
