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 group R.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, and n represents zero or an integer from 1 to 3. The invention further relates to the preparation of the above spirocarbocyclic compounds, intermediates prepared during the synthesis of these compounds, compositions containing the compounds and their use as fungicides in the control of phytopathogenic fungi.
本发明涉及一种新的抗微生物螺环烷化合物,其具有通式I,##STR1## 或其酸加成盐,其中R.sub.1代表可选取代的烷基、环烷基、环烷基烷基、烷氧基、环烷氧基、烷氧基烷基、芳基烷基;R.sub.2和R.sub.3各自独立地代表氢或可选取代的烷基、烯基、炔基、环烷基、环烷基烷基、双环烷基、三环烷基、烷氧基烷基、芳基烷基、芳基或卤代芳基烷基、4-至6-成员杂环基、四氢呋喃基或二氧杂环戊基;或R.sub.2和R.sub.3一起代表可选取代的饱和或不饱和链,该链可以可选地包含一个或多个氧原子,并且可以可选地与芳基或环烷基融合,n表示零或1至3的整数。本发明还涉及上述螺环烷化合物的制备,制备这些化合物期间制备的中间体,含有该化合物的组合物以及其作为杀菌剂在控制植物病原真菌方面的使用。
