Key Points

This research focuses on developing a Rh-catalyzed annulation method for synthesizing α-pyrazolo[1,2-a]indazole acrylates.
Utilized Rh-catalyzed (4+1)-annulation method
Leveraged MBH adducts as key C1-synthons
Employed air as an oxidant
Involved C-C and C-N bond formation
Successfully synthesized α-pyrazolo[1,2-a]indazole acrylates
Demonstrated C-C bond formation efficiency
Highlighted the role of MBH adducts in synthesis

Implication

Rh-catalyzed annulation enhances C-C bond formation in N-arylpyrazolidinones, indicating efficiency of MBH adducts.

Abstract

Rh-catalyzed (4+1)-annulation of N-arylpyrazolidinones with MBH adducts has been developed to furnish α-pyrazolo[1,2-a]indazole acrylates. The use of MBH adduct as C1-synthon, cascade C-C/C-N bond formation, air as the oxidant, substrate...
