The development of the sequential Corey–Chaykovsky reactions of isatins, spiroepoxy-, or spiroaziridine oxindoles with sulfur ylide has led to the discovery of a unique reaction mode that allows easy and direct one-pot access to a range of spirocyclopropyl oxindoles.
Disclosed is a compound as shown in formula (I), an optical isomer thereof or a pharmaceutically acceptable salt thereof, and the present invention relates to the use of same in the preparation of a drug for treating FXR-related diseases.

The Pd-catalyzed, Ag(I)-mediated intramolecular direct arylation of cyclopropane C H bonds is described. Various spiro 3,3'-cyclopropyl oxindoles can be obtained in good to excellent yields from easily accessible 2-bromoanilides. The kinetic isotope effect was determined and epimerization studies were conducted, suggesting that the formation of a putative Pd-enolate is not operative and that the reaction proceeds via a C-H arylation pathway.
