Haydl, Alexander M.; Xu, Kun; Breit, Bernhard published the artcile< Regio- and Enantioselective Synthesis of N-Substituted Pyrazoles by Rhodium-Catalyzed Asymmetric Addition to Allenes>, Application In Synthesis of 13808-65-6, the main research area is pyrazole terminal alkene addition rhodium catalyst; allylated pyrazole asym preparation; allenes; allylic compounds; asymmetric catalysis; heterocycles; rhodium.
The rhodium-catalyzed asym. N-selective coupling of pyrazole derivatives with terminal allenes gives access to enantioenriched secondary and tertiary allylic pyrazoles, i.e. I, which can be employed for the synthesis of medicinally important targets. The reaction tolerates a large variety of functional groups and labeling experiments gave insights into the reaction mechanism. This new methodol. was further applied in a highly efficient synthesis of JAK 1/2 inhibitor (R)-ruxolitinib.
