  • Patent number: 4870088
    Abstract: 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.
