Abstract
A direct and much simpler way was developed for the diastereoselective synthesis of spiro cyclopropan-1,3′-oxindoles from indolin-2-one/N-protected indolin-2-ones and bromonitroalkene. The fused restrained cyclopropanes were obtained with high diastereomeric ratios (upto >99:1) and in reasonable to high isolated chemical yields (upto 94%).
