Abstract: A process for preparing a compound of formula 1 from a compound of formula 2 the process comprising reacting in one step the compound of formula 2 with a compound of formula 3 wherein: X− is chlorine, bromine, iodine, methanesulfonate, or trifluoromethanesulfonate; R1 is hydroxy, C1-C4-alkyl, C1-C4-alkoxy, CF3, or fluorine; Ar is phenyl, naphthyl, thienyl, and furyl, each optionally mono- or disubstituted with one or two groups selected from C1-C4-alkyl, C1-C4-alkoxy, hydroxy, fluorine, chlorine, bromine, or CF3; Y− is chlorine, bromine, iodine, methanesulfonate, or trifluoromethanesulfonate; and R is hydroxy, methoxy, ethoxy, O—N-succinimide, O—N-phthalimide, phenyloxy, nitrophenyloxy, fluorophenyloxy, pentafluorophenyloxy, vinyloxy, 2-allyloxy, —S-methyl, —S-ethyl, or —S-phenyl.

Abstract: New antimicrobial spirocarbocyclic compounds are described, having the general formula I, ##STR1## or an acid-addition salt thereof, in which R.sub.1 represents an optionally substituted alkyl, cycloalkyl, cycloalkylalkyl, alkoxy, cycloalkoxy, alkoxyalkyl, aralkyl groupR.sub.2 and R.sub.3 each independently represent hydrogen or an optionally substituted alkyl, alkenyl, alkynyl, cycloalkyl, cycloalkylalkyl, bicycloalkyl, tricycloalkyl, alkoxyalkyl, aralkyl, aryl or haloaralkyl, a 4- to 6-membered heterocyclyl, tetrahydrofuryl or dioxolanyl group, or R.sub.2 and R.sub.3, together represents an optionally substituted, saturated or unsaturated chain which may optionally contain one or more oxygen atoms and which may optionally be aryl- or cycloalkyl-fused, andn represents zero or an integer from 1 to 3.

Abstract: New fungicidal spiroheterocyclic compounds are described, having the general formula I, ##STR1## or an acid-addition salt thereof, in which R.sup.1, R.sup.2, R.sup.3, R.sup.4 and R.sup.5 are as defined in the specification. A process of preparing such compounds is also described.
