  • Patent number: 4304919
    Abstract: The invention relates to asymmetrical thioindigo compounds of the formula I ##STR1## wherein at least one substituent R is different from a substituent R' and preferably at most three Rs or R's are different from hydrogen, e.g. the compound (I), wherein theRs and R's in the positions 4, 6, 7, 4', 6' and 7' are hydrogen, the R in position 5 is methyl and the R' in position 5' is --(CH.sub.2) OCOCH.sub.3. These compounds can be obtained by a novel process in simple and economic manner and in high purity by reacting a compound of the formula II ##STR2## (wherein X is halogen) with corresponding thiophenols, and cyclising the unsubstituted or substituted 2-thiophenyl-carboxymethylene-benzothiophen-3-ones thereby obtained. Some of the compounds of the formula I are known per se and they are used, inter alia, as disperse, melt spinning and pigment dyes.

  • Patent number: 4221800
    Abstract: Certain substituted cycloalkenochromones and pharmacologically acceptable salts thereof are disclosed as being useful in the treatment of allergies. The compounds have the structure: ##STR1## X is --O--, --S--, or --SO.sub.2. Y is from 1 to 4. R.sub.1 is H or alkyl, and R.sub.2 is H, alkyl, aryl, carboxyl, alkoxy, aralkoxy, or alkoxycarbonyl. When R.sub.1 is alkyl, R.sub.2 is hydrogen, alkyl or aryl. At least one of R.sub.2 and R.sub.3 is alkoxycarbonyl, carboxyl or tetrazolyl. R.sub.3 is carboxyl, alkylthio, alkylsulfonyl, alkylsulfinyl, alkoxycarbonyl, or tetrazolyl.
