(figure presented) A series of novel heterocyclic derivatives of (–)-borneol has been prepared by the interaction of (1S,2R,4S)-1,7,7-trimethylbicyclo[2.2.1]-heptan-2-yl 2-chloroacetate and (1S,2R,4S)-1,7,7-trimethylbicyclo[2.2.1]heptan-2-yl 3-chloropropanoate with different N- and S-nucleophiles. The obtained products were screened for antiviral, antiulcer, and analgesic activity.

The invention belongs to the technical field of photocatalytic organic synthesis, and discloses a preparation method of bio-derived isobornyl (meth) acrylate. The method comprises the following steps:adding camphene, (methyl) acrylic acid, a polymerization inhibitor and a catalyst into a transparent reactor, uniformly mixing, placing under UV light irradiation, carrying out a stirring reaction, and carrying out reduced pressure rotary evaporation after the reaction is finished to obtain isobornyl acrylate and isobornyl methacrylate. According to the method, isobornyl (meth) acrylate is prepared by adopting a photocatalysis method, wherein the reaction conditions are mild, the reaction time is short, side reactions and byproducts are avoided, the conditions of high temperature, high pressure and the like are not needed, the separation and purification are simple and easy to operate, and the isobornyl (meth) acrylate can be obtained. According to the invention, isobornyl (meth) acrylateis prepared from a natural renewable resource camphene, so that a new application direction is opened up for the natural renewable resource vegetable oil, the economic value of the vegetable oil is improved, and the method has a good popularization effect on the development of agriculture and forestry economy.
