摘要:Novel thienobenzopyrans and thiopyranobenzopyrans represented by the formula ##SPC1## n Wherein m and n are each 0, 1, 2 or 3 and m + n is 2 or 3; R 1 is loweralkyl; R 2 is alkyl or cycloalkylloweralkyl and R 3 is hydrogen, loweralkyl, loweralkanoyl, carbamyl, N-loweralkylcarbamyl, N,N-diloweralkylcarbamyl, phosphonyl, hemisuccinate or an ester of another such acid, phosphate, dialkylaminoalkyl of the structure ##EQU1## or acid addition salt thereof, or dialkylaminoalkylanoyl of the structure ##EQU2## or acid addition salt thereof, wherein x is 1 through 6 and R 4 and R 5 are loweralkyl; the loweralkyl groups containing from 1 through 6 carbon atoms, the alkyl groups containing from 1 through 20 carbon atoms and the cycloalkyl groups containing from 3 through 8 ring carbon atoms. Novel intermediates for the synthesis of these compounds are also disclosed as well as methods for making the compounds.
