Rh(III)-catalyzed sequential spiroannulation/lactonization of 3-aryl N-sulfonyl ketimines with 4-hydroxy-2-alkynoates by C –H bond activation

New J. Chem., 2024, Advance Article DOI: 10.1039/D3NJ04312F, PaperS. Prashanth, Chidrawar Ajay, Kommu Nagesh, B. Sridhar, B. V. Subba Reddy A rhodium(III)-catalyzed C –H annulation strategy has been developed for the synthesis of a highly rigid spirobenzosultam lactones in good yields with high regioselectivity from 3-arylN-sulfonyl ketimines and 4-hydroxy-2-alkynoates.
