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.
化合物I为##STR1##其中A等于叔丁基或大量的(取代的)芳香族基团;Y等于唑基;或Y等于--X--R.sup.1,其中X为氧或
硫,R.sup.1为(环状)烷基或(杂环)芳基;或Y等于##STR2##其中R.sup.2为(环状)烷基、乙酰基或芳基;或Y等于--NR.sup.3 R.sup.4,其中R.sup.3/R.sup.4为烷基;或Y等于几个含氮的杂环环;Z等于OH、烷基羰氧、卤素、烷氧基或苄氧基;它们的盐是有效的抗真菌剂或杀菌剂。它们通过化合物II ##STR3##与(CH.sub.3).sub.2 ##STR4##的反应以及从中得到的化合物IV ##STR5##与核苷酸YM(M=氢或
金属当量)的进一步反应获得。由此产生的化合物I(其中Z=OH)可以酰化或烷基化,或转化为Z=卤素的I。
