Discovered the Ruthenium(II) catalysed highly stereo- and regioselective protocol for the oxidative C-3 alkenylation of indolizines and pyrrolo[1,2-a]quinolines. The methodology represents the first example for the directing group assisted C–C bond formation reaction of the indolizines. Under mild reaction conditions, this method provides an ample substrate scope to produce C-3 alkenyl indolizines in excellent to moderate yields. However, pyrrolo[1,2-a]quinolines underwent alkenynation at elevated temperature to furnish C-3 alkenyl derivatives. The functionalized indolizines were selectively reduced to obtain their saturated derivatives.

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.
