ammonia, and carboxylic acids are the precursors for the efficient synthesis of 4‐hydroxypyridines and the corresponding nonaflate derivatives. This provides simple and practical access to a variety of highly substituted pyridine derivatives, including antibiotic natural products such as caerulomycins A, E and functionalizedterpyridines (see scheme).
