    摘要: A new class of anti-spasmodic compounds having three branch chains is provided. These compounds have the general formula: ##STR1## where R.sub.1, R.sub.2 and R.sub.3 are saturated straight chain or branched alkyl groups contained from 1 to 8 carbon atoms, and are separated or linked to one another to form an aliphatic ring system. k is an integer from 0 to 5, and the total number of carbon atoms in R.sub.1 plus R.sub.2 plus R.sub.3 plus k are equal to or less than 12. Furthermore, l is an integer from 1 to 3, m is an integer from 1 to 3, n is an integer from 1 to 3, and X may be nonexistent or may be O, S, NH or CH.sub.2 or salts thereof. However, when X is nonexistent the terminal group in both the m chain and the n chain is a methyl group.

    摘要: This invention relates to a process for the optical resolution of DL-.alpha.-methyl-.beta.-acylthiopropionic acids of the formula [I], ##STR1## wherein R is a lower alkyl group having 1-4 carbon atoms, phenyl or substituted phenyl bearing methyl or chloro radical; a method for the racemization of an optically active .alpha.-methyl-.beta.-acylthiopropionic acid of the formula [Ia], ##STR2## wherein R is as defined above; and a process for the synthesis of captopril of the formula [II], ##STR3## using the D-acid [Ia] as an intermediate. The optically active .alpha.-methyl-.beta.-acylthiopropionic acids are useful as intermediates for the production of medicines, for example, captopril or its congeners.
