Paragraph 0205; 0206, (2017/02/28)
The present invention relates to a five-membered azole heterocycle compound represented by the following general formula (I), a preparation method of the five-membered azole heterocycle compound, a drug composition of the five-membered azole heterocycle compound, and a use of the five-membered azole heterocycle compound in preparation of drugs for prevention or treatment of TGR5-mediated diseases. The formula (I) is represented by the instruction.
Switching pathways: Room-temperature neutral solvolysis and substitution of amides

Stick or twist: By introducing steric hindrance at the nitrogen atom, stable linear amides bearing an electron-withdrawing α-substituent (Z=Ar, PhSO2, P(O)(OR)2, CN, or CO2R) can be induced to undergo solvolysis and substitution reactions through an elimination-addition mechanism (see picture). Key to this process is a low barrier to rotation around the amide bond and the α-substituentZ. Copyright
