摘要:
Novel compounds of the formula (1) ##STR1## wherein R.sup.1 and R.sup.2 are different lower alkyls and R.sup.3 is a lower alkyl or a methyl pyridine group, and the acid addition salts of formula (1) compounds when R.sup.3 is methyl pyridine. The novel compounds have an asymmetric C-atom and may be in the form of the D,L racemates or the D or L stereoisomers.These compounds are useful in the treatment of hypercholesterolemia and hyperlipidemia because of their high effectiveness in reducing the level of cholesterol and lipids in the blood combined with very low general toxicities and substantially reduced hepatomegalitic effects.
