    • The invention relates to new bicyclo(2.2.1)heptane derivatives of the general formula I ##STR1## wherein R represents a C.sub.1-12 alkyl group optionally substituted by a lower alkoxy group, a C.sub.2-4 alkenyl group or a phenyl-(lower alkyl) group optionally substituted on the phenyl ring by one or more lower alkoxy groups or halogen atoms.The invention relates further to plant growth regulating compositions comprising as active agent 0.001 to 95% by weight of a racemic and/or optically active compound of the general formula I, wherein R has the above defined meanings, along with a conventional organic or inorganic, solid and/or liquid carrier and/or filler and/or diluent and/or surfactant.The invention encompasses also the preparation of the compounds of the general formula I which comprises reacting a racemic or optically active compound of the general formula II ##STR2## wherein Y is an oxygen or sulfur atom or an oxim group, with a compund of the general formula IIIR - XwhereinR is as defined above, andX represents a leaving group, preferably a halogen atom, a sulfonyloxy or an aminooxy group, with the proviso that when using a compound of the general formula II, in which Y is an oxim group, X is other than aminooxy group,in the presence of a basic condensing agent, and optionally resolving the racemic compound of the general formula I obtained into its optically active antipodes.
    • 本发明涉及通式I的新的双环(2.2.1)庚烷衍生物,其中R表示任选被低级烷氧基,C 2-4链烯基或苯基 - ( 低级烷基)基团,其任选在苯环上被一个或多个低级烷氧基或卤素原子取代。 本发明进一步涉及植物生长调节组合物,其包含作为活性剂0.001至95重量%的通式I的外消旋和/或旋光活性化合物,其中R具有上述定义的含义,以及常规的有机或无机, 固体和/或液体载体和/或填料和/或稀释剂和/或表面活性剂。 本发明还包括通式I的化合物的制备,其包括使通式II的外消旋或旋光活性化合物其中Y是氧或硫原子或肟基,与下列化合物反应: 通式III R-X其中R如上定义,X​​表示离去基团,优选卤素原子,磺酰氧基或氨基氧基,条件是当使用通式II的化合物时,其中Y为 肟基,X不是氨基氧基,在碱性缩合剂的存在下,并且任选地将所得通式I的外消旋化合物拆分成其光学活性对映体。
