visnagin-9-sulfonyl esters underwent cleavage of their pyran ring upon treatment by hydroxylamine hydrochloride, hydrazine hydrate and primary amines. Reaction of visnagin-9-sulfonyl chloride 1 with alcohols or phenol gave the corresponding sulfonate derivatives 2, that were treated with hydroxylamine hydrochloride, anilines or hydrazine derivatives to give the corresponding compounds 3–5, respectively
