Stereoselective cycloaddition of nitrile oxides to a dispiroketal-protected but-3-ene-1,2-diol
Gravestock,Paton,Todd
, p. 2723 - 2730 (1995)
The influence of a dispiroketal protecting group on the π-facial selectivity of nitrile oxide cycloaddition of S-but-3-ene-1,2-diol has been investigated. Ethoxycarbonylformonitrile oxide and benzonitrile oxide undergo regiospecific and diasteroeselective addition to alkene 7 to afford isoxazolines 11 and 12. The major adducts (11a and 11b) are formed with 44% and 50% d.e. respectively, and in each case have S-configuration at C-5, the new stereogenic centre.

We demonstrate the novel spiroannulation of exo-imines with 1,3-dipoles, for the first time, leading to 3D spirocycles with a secondary amine (NH) in the spiro-ring. The synthetic method described herein allows access to these previously unexplored heterospirocyclic cores that have application in the discovery of functional molecules for medicinal and materials science. This was demonstrated by discovering an unprecedented class of heterospirocycles with antimalarial activity against the human protozoan P. falciparum.
