M. Morenomanas et al., PALLADIUM-CATALYZED ALLYLATION OF 3-HYDROXYISOXAZOLE, 5-ISOXAZOLONE AND 5-PYRAZOLONE SYSTEMS, Tetrahedron, 50(2), 1994, pp. 515-528
Kinetic vs. thermodynamic control and steric hindrance are factors tha
t determine the regioselectivity of the Pd(0)-catalyzed allylation of
ambident heterocycles of the 3-hydroxyisoxazole, 5-isoxazolone and 5-p
yrazolone series.
