Abstract

Fungicidally active 2-aminomethyltetrahydrofurans of the formula ##STR1## in which R.sup.1 represents in each case optionally substituted aryl, heteroaryl, cycloalkyl, tetrahydronaphthyl or decahydronaphthyl; PA1 R.sup.2 represents hydrogen or methyl; and PA1 R.sup.3 and R.sup.4, independently of one another, in each case represent hydrogen, alkyl, alkenyl, alkinyl, alkoxyalkyl, dialkoxyalkyl, hydroxyalkyl, hydroxyalkoxyalkyl, dioxolanylalkyl, oxolanylalkyl, dioxanylalkyl, or in each case optionally substituted cycloalkylalkyl, cycloalkyl, aralkyl, aralkenyl or aryl, or PA1 R.sup.3 and R.sup.4, together with the nitrogen atom to which they are bound, represent an optionally substituted saturated heterocyclic ring which may optionally contain further heteroatoms, or acid-addition salts thereof.
