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 III R - X wherein R is as defined above, and X 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.
该发明涉及一种新的脱氢环庚烷衍生物,其一般式为I,其中R代表一个C.sub.1-12烷基基团,该基团可以选择性地被一个较低的烷氧基团、一个C.sub.2-4烯基基团或一个苯基-(较低烷基)基团所取代,该苯基基团在苯环上可以被一个或多个较低烷氧基团或卤原子取代。该发明还涉及植物生长调节组合物,其包含作为活性剂的一般式I的消旋和/或光学活性化合物,其中R具有上述定义的含义,以及传统的有机或无机、固体和/或液体载体和/或填料和/或稀释剂和/或表面活性剂。该发明还包括制备一般式I化合物的方法,其中包括将一般式II的消旋或光学活性化合物与一般式III的化合物反应,其中Y是氧或硫原子或氧肟基,R如上所定义,X代表一个离去基团,最好是一个卤原子、磺酰氧基团或氨氧基团,但是当使用Y为氧肟基的一般式II中的化合物时,X不是氨氧基团,在存在碱性缩合剂的情况下,并且可以将所得的一般式I的消旋化合物分解为其光学活性对映体。
