    Abstract: wherein X is halogen, in the presence of an alkali metal base.

    WHEREIN A is either CH2-CH2 or CH CH, >Z is >C O, >CH-OH or >CH2, and R1 is hydrogen, alkyl, alkanoyl, aryl or aryl alkyl, and R is lower alkylene, are useful as animal growth promoters. The compounds may be prepared by reacting a resorcyclic acid lactone derivative with a compound of the formula

    New resorcyclic acid lactone derivatives which may be represented by the formula

    Abstract translation: 可以由式WHEREIN A表示的新的重链内酯衍生物是CH 2 -CH 2或CH = CH,> Z是> C = O,> CH-OH或> CH 2,并且R 1是氢,烷基,烷酰基,芳基 或芳基烷基,R为低级亚烷基,可用作动物生长促进剂。 化合物可以通过在碱金属碱的存在下使重环己内酯衍生物与式O的化合物OR PARALLEL ROCOC-R-X(其中X是卤素)反应来制备。
