Extending the scope of the [2+2] cycloaddition of dichloroketene to chiral enol ethers: Synthesis of (-)-detoxinine

Ceccon, Julien,Poisson, Jean-Fran?ois,Greene, Andrew E.

, p. 1413 - 1416 (2007/10/03)

Allylic oxidation of a known lactam, obtained by asymmetric [2+2] cycloaddition of dichloroketene to a chiral enol ether, followed by Beckmann ring expansion and dechlorination, affords a potential intermediate for the synthesis of various natural product
