A number of substituted 4-methoxy-7-methyl-6-(substituted methyl)-5-oxo-5H-furo[3,2-g]-chromene-9-sulfonates 3a-3f and 4a-4c were synthesized. Treatment of visnagin-9-sulphonyl esters by secondary amines gave the substituted 6,7-dihydro-4-methoxy-7-methyl-7-substituted-5-oxo-5H-furo[3,2-g]-chromene-9-sulfonates 5a-5f and 6a-6c. Some of synthesized compounds were tested as potential alpha-blocking and antiarrythmic agents.

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
