An Efficient Synthesis of a Spirocyclic Oxindole Analogue
An efficient, scaleable synthesis approach towards the spirocyclic oxindole analogue 1’-(tert-butoxycarbonyl)-2-oxospiro[indoline-3,4’-piperidine]-5-carboxylic acid (1) is described. The key steps are dianion alkylation and cyclization of ethyl 2- oxindoline-5-carboxylate (4) and demethyla...
