Compounds I ##STR1## where A equals t-butyl or a large number of (substituted) aromatics; Y equals azolyl; or Y equals --X--R.sup.1 where X=oxygen or sulfur and R.sup.1 equals (cyclo)alkyl or (heterocyclic) aryl; or Y equals ##STR2## where R.sup.2 equals (cyclo)alkyl, acetyl or aryl; or Y equals --NR.sup.3 R.sup.4 where R.sup.3 /R.sup.4 is alkyl; or Y equals several nitrogen-containing heterocyclic rings; Z equals OH, alkylcarbonyloxy, hal, alkoxy or benzyloxy; and the salts thereof are effective antimycotics or fungicides. They are obtained by reaction of II ##STR3## with (CH.sub.3).sub.2 ##STR4## and further reaction of the compound IV ##STR5## obtained from this with a nucleophile YM (M=hydrogen or a metal equivalent). The compounds I (where Z=OH) resulting from this can be acylated or alkylated, or converted into I where Z=hal.

Antimycotic 1,1-disubstituted cyclopropane derivatives

New 1-(1,3-dioxolan-2-ylmethyl)azoles, their stereoisomers and their salts are described, as are processes for their preparation. The new compounds are chemotherapeutic agents. They are active against skin fungi, mold fungi and yeasts and against bacteria.

1-(1,3-dioxolan-2-ylmethyl)azoles, their salts and their use

The preparation of (optionally substituted) 2-mercaptobenzothiazole by reaction of corresponding 2-halogenoanilines with an alkali metal xanthate or alkaline earth metal xanthate or with CS.sub.2 in the presence of bases.

Process for the preparation of 2-mercaptobenzothiazoles

1-(1,3-Dioxolan-2-ylmethyl)-azoles of the general formula ##STR1## and their stereoisomers and their salts with physiologically acceptable acids, the preparation of these compounds, pharmaceutical formulations containing the latter and their use against mycoses, protozoa and Gram-positive and Gram-negative bacteria are described.
