N-羟基邻苯二甲酰亚胺用膦催化[3 + 2]缺电子炔的环化反应:3a-羟基异恶唑并[3,2 - a ] isoindol-8(3a H)-ones的合成
摘要:
AbstractThe phosphine‐catalyzed [3+2] annulation of electron‐deficient alkynes with N‐hydroxyphthalimide has been developed to give a variety of pharmaceutically attractive 3a‐hydroxyisoxazolo[3,2‐a]isoindol‐8(3aH)‐ones in good to excellent yields.magnified image
