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.
