Abstract
Novel 3-hydroxy-4-alkyloxyphenyl heterocyclic carbonates suited as sweeteners in foodstuff, said carbonates having the following basic structure: ##STR1##
Claims10
A compound of the formula:
- ##STR6## wherein:
- R is methyl or ethyl;
- R.sub.1 is of the formula:
- ##STR7## wherein Z is a five-membered heterocyclic ring in which the hetero atom is at least one of S, O, N and NR.sub.2 ;
- wherein n is an integer from 0 to 1 when Z is a fully-saturated heterocyclic ring and, otherwise n=1;
- each R.sub.2 is selected from the group consisting of H, CH.sub.3, CH.sub.2 CH.sub.3, CH.sub.2 CH.sub.2 CH.sub.3, CH(CH.sub.3).sub.2, OH, OCH.sub.3, CH(OH)CH.sub.3, OCH.sub.2 CH.sub.3, OCH(CH.sub.3).sub.2, CH.sub.2 OH, CH.sub.2 CH.sub.2 OH, CH.sub.2 CHOHCH.sub.3, CH.sub.2 OCH.sub.3, CHO, COCH.sub.3, COCH.sub.2 CH.sub.3, CH.sub.2 COCH.sub.3, and COOCH.sub.3 with the proviso that R.sub.1 contain no more than 12 carbon atoms;
- and
- salts thereof.
