Abstract

Reaction of 4-substituted isoxazolo[4,5-c]- and [5,4-b]pyridines with Mo(CO)₆ in refluxing methanol is an efficient and versatile procedure for the preparation of functionalized pyrido-condensed heterocycles containing from five to eight atoms in the ring.

Key words

condensed pyridines - molybdenum hexacarbonyl - ring opening - rearrangements - benzodiazocines
