    摘要: Amides of carnitine or acyl-carnitines having general formula: ##STR1## wherein X.sup.- is a halogen anion, e.g. the chloride anionR is either hydrogen or an acyl radical, such as acetyl, propionyl or butyryl; andY is the residue of an optically active esterified amino-acid (e.g. the residue of L-phenylglycine methyl ester, ##STR2## are prepared by either (a) directly condensing D,L-carnitine (or acyl-D,L-carnitine) with an ester of an optically active aminoacid, or (b) preparing the acid halogenide of D,L-carnitine or acyl-D,L-carnitine and subsequently condensing it with an ester of an optically active aminoacid.The mixture of the diastereoisomer amides thus obtained is resolved by fractional crystallization from organic solvents into the respective separated diastereoisomers.These optically active amides are useful therapeutic agents for treating cardiac disorders, hyperlipidaemias and hyperlipoproteinaemias and, furthermore, can be hydrolyzed with procedures known per se into L-carnitine and D-carnitine, respectively.
