| abstract | Process for preparing sulfonates and carboxylatesn(E) -3- (hydroxymethylene) hexahydro-2 (3H) -benzofuranonenof Formula InOXn/ 1 /,nOnwherein X is acetyl, benzoyl, methanesulfonyl,ntrifluoromethanesulfonyl, benzenesulfonyl,n4-Toluenesulfonyl, which are prepared asnto about 1% to saturated sodium salt solutionn3- (hydroxymethylene) hexahydro-2- (3H) -benzofuranonenin a polar solvent such asnfor example aqueous acetone, aqueous tetrahydrofurannand water, in the presence of nitrogenousnbases act with chlorides or bromides ornsulfonic or carboxylic anhydridesnacids of formula XC1 or XBr ornXOX, wherein X is as defined above. Sulfonatesnand carboxylates (E) -3- (hydroxymethylene) -nhexahydro-2 ' -H-benzofuran are reactivencompounds with extensive synthetic use,npotentially potentialnantitumor effects and as the defaultnsubstrates for the preparation of other substancesnwith these effects. |
