ABSTRACT:
The present invention is a compound of the formula ##STR1## wherein R.sup.1 and R.sup.2 are independently C.sub.1-20 alkyl unsubstituted or substituted with a C.sub.1-3 alcohol, or allyl unsubstituted or substituted with a C.sub.1-4 alkyl or phenyl, R.sup.3 and R.sup.4 are independently hydrogen, or C.sub.1-20 alkyl unsubstituted or substituted with a C.sub.1-3 alcohol or together R.sup.3 and R.sup.4 are oxygen, and R.sup.5 and R.sup.6 are independently C.sub.1-20 alkyl unsubstituted or substituted with C.sub.1-3 alcohol or phenyl, hydroxy, --(CH.sub.2).sub.1-3 COOH, --CHR.sup.7 COOH wherein R.sup.7 is C.sub.1-5 alkyl or C.sub.1-5 alkyl substituted with hydroxy, amino, or carboxy, or allyl unsubstituted or substituted with a C.sub.1-4 alkyl or phenyl or together R.sup.5 and R.sup.6 with the two nitrogen atoms form a fused ring having the formula ##STR2## wherein n is 1 or 2, or form a fused ring having the formula ##STR3## wherein p is an integer from 0 to 3.
