Method for preparing meta-position alkenyl aromatic compound
-
Paragraph 0011, (2020/02/17)
The invention discloses a method for preparing a meta-position alkenyl aromatic compound. The meta-position alkenyl aromatic compound is prepared from a meta-position formyl aromatic compound and diethyl benzylphosphonate through a reaction, and the reaction comprises steps of directly adding the meta-position formyl aromatic compound, the diethyl benzylphosphonate, ammonium acetate, iodine, peroxytert-butanol, sodium carbonate and ethanol into a reaction device, performing stirring and heating to a temperature of 45-55 DEG C, performing the reaction for 7-9 hours, and separating products, soas to obtain the meta-position alkenyl aromatic compound. By adopting the method, the meta-position alkenyl aromatic compound can be conveniently and rapidly synthesized.

Sant-75 is a newly identified potent inhibitor of the hedgehog pathway. We designed a diversity-oriented synthesis program, and synthesized a series of Sant-75 analogues, which lays the foundation for further investigation of the structure-activity relationship of this important class of hedgehog-pathway inhibitors.
