position of the formyl group on the efficiency of Baylis-Hillman reaction within isoxazolecarbaldehydes, the reactions of substituted 4-isoxazole-carbaldehydes to obtain highly substituted isoxazoles are described. Attempts to obtain isoxazole-annulated derivatives from these Baylis-Hillman adducts involving S N R'-S N Ar substitution strategy are also described.
为了了解甲酰基的位置对异恶唑甲醛中 Baylis-Hillman 反应效率的影响,描述了取代的 4-异恶唑-甲醛获得高度取代的异恶唑的反应。还描述了从这些涉及 SN R'-SN Ar 取代策略的 Baylis-Hillman 加合物中获得异恶唑环化衍生物的尝试。
