M. Toyota et al., INOC REACTION IN GIBBERELLIN SYNTHESIS - A PRACTICAL SYNTHESIS OF THEKEY INTERMEDIATE FOR GIBBERELLIN A(12), Heterocycles, 41(6), 1995, pp. 1135-1138
The isoxazoline (10), a possible key intermediate for gibberellin A(12
) (1), has been synthesized in 91% yield by means of intramolecular ni
trile oxide cycloaddition (INOC) reaction of the oxime (9).
