Abstract
We report a short synthetic route to (±)-horsfiline that provides the racemate in five steps from commercially available, substituted isatin in 41% overall yield. Efficient entry into the spiro[oxindole-pyrrolidine] ring system is possible through the application of the cyclopropane opening/ring expansion chemistry we have described with MgI2 as a bifunctional catalyst.
