Application
Tetrakis[(S)-(+)-[(1S)-1-(4-bromophenyl)-2,2-diphenylcyclopropanecarboxylato]dirhodium(II) Rh2(S-BTPCP)4 serves as a chiral catalyst primarily designed for the enantioselective formation of cyclopropanes through the reaction of aryls with styryl diazoacetates. This compound plays a crucial role in asymmetric synthesis processes, facilitating the formation of bicyclo[1.1.0]butane rings via the rhodium-catalyzed decomposition of 2-diazo-5-arylpent-4-enoates. Additionally, it is employed in the synthesis of 2.5-dihydroisooxazoles through reactions involving vinyldiazoacetates and nitrones, showcasing its versatility and efficiency in complex organic transformations.
