The synthesis and structure-activity relationships of N-phenyl-N′-[3- (4-phenylnaphthylidinoyl)]urea derivatives 3 as a novel structural class of potent ACAT inhibitors is described. A 3-methoxy group substituted on the naphthylidinone 4-phenyl ring, toge

Chemoselective directed metallation of 2-chloropyridine allows the synthesis of 2-substituted 3-carbonylated pyridines, advantage being taken of the metallation ortho-directing effect of the halogen, as well as its reactivity towards nucleophiles.Thus (2-chloro-, 2-methoxy-, and 2-amino-3-pyridyl)-ethanones and -arylmethanones as well as carbaldehydes have been prepared.Some of these ortho-disubstituted intermediates have been readily cyclized to fused polyheterocycles such as naphthiridines and aza-analoges of coumarins, xanthones, and acridones.

Lithium diisopropylamide reacts with 2-fluoropyridine at low temperature: regioselectivity is excellent and metallation occurs without side reactions such as nucleophilic attack. 2-Fluoro-3-lithiopyridine is formed and with aldehydes it gives the correspo
