dc.description.abstract	An efficient diastereoselective synthesis of oxindoleappended vinyl cyclopropanes from bromo isomerised Morita Baylis-Hill man adducts of isatin with activated alkylidene and isatilidines via sulfur ylide cyclopropanation reaction have been achieved.The synthesised vinyl cyclopropanes have undergone vinyl cyclopropane rearrangement and [3+2) cyclo addition with an allene to afford dispiro bisoxindole bridged by cyclopentene and spirocyciopentene-2-oxindole-bridged spirocyclopropane-2-oxindole derivatives respectively.	en_US
