The novel benzoxathiinopyridines 8 and 9 were synthesized by ring transformation of phenyl 4‐chromone‐3‐sulfonate ( 1 ) with methyl 3‐aminocrotonate ( 2 ). The structures of 8 and 9 were determined by spectroscopic methods and the reaction courses for the formation of these compounds are discussed.
