    摘要: A compound of the formula: ##STR1## wherein A is a carbonyl group or a sulfonyl group;B is either one of the formulas: ##STR2## (in which E is a methylene group, an ethylene group or an oxygen atom and a full line accompanying a broken line ( ) indicates a single bond or a double bond), ##STR3## (in which F is a methylene group or an ethylene group and a full line accompanying a broken line ( ) is as defined above) and ##STR4## (in which R.sup.1, R.sup.2, R.sup.3, R.sup.4, R.sup.5 and R.sup.6 are each a hydrogen atom or a methyl group) when A represents a carbonyl group, or B is a 1,2-phenylene group when A represents a sulfonyl group;D is an ethylene group, an ethenylene group or an ethynylene group, of which one or more may be optionally substituted with hydroxyl; andn is an integer of 0, 1 or 2, or its acid addition salt. These compounds are useful for the treatment or psychosis.

    摘要: A process for the optical resolution of DL-.alpha.-methyl-.beta.-acylthiopropionic acid, which comprises contacting a DL-.alpha.-methyl-.beta.-acylthiopropionic acid of the formula, ##STR1## wherein R.sub.1 is acetyl or benzoyl which may be substituted with a C.sub.1 -C.sub.3 alkyl or a halogen atom, with an optically active amine of the formula, ##STR2## wherein R.sub.2 is methyl, isopropyl or isobutyl, to form diastereoisomeric salts, subjecting the formed diastereoisomeric salts to the fractional crystallization in a solvent to separate the D-acid salt from the L-acid salt, and then contacting the individual diastereoisomeric salt with acid to give D-.alpha.-methyl-.beta.-acylthiopropionic acid and L-.alpha.-methyl-.beta.-acylthiopropionic acid, the former being useful as an intermediate for synthesizing captopril useful as an antihypertensive agent.
