    • PURPOSE: A process for isomerizing fused bicyclic structures is provided to ensure high yield, high isomerization rate, and convenient experiment conditions, thereby being suitable for an industrial process. CONSTITUTION: A preparation process of a cis fused bicyclic derivative from a corresponding trans fused bicyclic derivative comprises the step of reacting the trans fused bicyclic derivative with an hydride base. The fused bicyclic derivative comprises an optionally cyloakanone substituted with an optionally substituted cycloalkane. The trans and cis fused bicyclic structures are respectively of formula (I) and (II), wherein R1 represents H or a C1-C6 alkyl group; R2 represents H or D, wherein D represents a deuterium atom; R3 represents a C1-C20 alkyl, optionally comprising one or more double or triple bonds, and/or optionally comprising one or more heteroatom(s) selected from O, N, S, Si; m is an integer chosen from 0, 1, 2, 3; n is an integer chosen from 0, 1 or 2; when present, each Ri and Rj, identical or different, respectively represent 1 to n or 1 to m groups, identical or different from each other, are independently selected from halogen atom, C1-C6 alkyl, C2-C20 alkenyl OR, NRR', CN, NO2, perhalogeno(C1-C6)alkyl, COR, COOR, CONRR', alkylaryl, alkenylaryl, where R, R', identical or different, are selected from H, alkyl, aryl.
