Total synthesis of (+/-)-welwitindolinone a isonitrile

J Am Chem Soc. 2006 Feb 8;128(5):1448-9. doi: 10.1021/ja057640s.

Abstract

A highly stereoselective total synthesis of the alkaloid natural product welwitindolinone A isonitrile has been completed. The synthesis utilizes a chloronium ion mediated semi-pinacol rearrangement to simultaneously install the C10 quaternary center and neopentyl chlorine and a novel anionic cyclization to construct the spiro-oxindole with complete stereocontrol.
