  The cleavage of the isoxazole ring during the Raney-Ni-promoted catalytic hydrogenation is prevented under the influence of 3-(substituted nitrophenyl)-2-isoxazoline in isoxazoline-substituted isoxazole systems produced via 1,3-dipolar cycloaddition either on the Baylis–Hillman derivatives or Grignard products. Unexpectedly, the hydrogenations in these diastereomeric compounds were observed to exclusively

  给出了在阮内镍和钯-碳存在下从取代的3-，4-和5-异恶唑羧醛及其相应的乙酸盐获得的Baylis-Hillman加合物催化加氢的结果。取代的5- isoxazolecarbaldehydes和在阮内镍的存在下3-isoxazolecarbaldehydes的的Baylis-希尔曼加合物的氢化的配料非对映选择性顺式烯胺酮过抗并在硼酸的存在下有利于非对映选择性的添加剂进一步增强顺式异构体，观察到。Pd–C促进的这些底物的氢化也具有非对映选择性，有利于合成异构体，但不发生异恶唑环的氢解。在该氢化中硼酸作为添加剂的存在对非对映选择性没有显着影响。Raney-Ni介导的取代的4-异恶唑甲醛的Baylis-Hillman加合物的加氢反应产生吡啶酮衍生物，而Pd-C促进的同一底物的加氢反应是非对映选择性的，从而提供了所得产物的反异构体。衍生自3-和5-异恶唑甲醛的Baylis-Hillman加合物的烯胺酮可作为α'-羟基-1
