Scope and limitations of the T-reaction with emphasis on using chiral, natural products as starting materials to prepare novel chiral heterocycles is studied and the diastereoselective introduction of newly formed stereocenters is explained via proposed mechanisms.
研究了 T 反应的范围和局限性,重点是使用手性天然产物作为起始材料制备新型手性杂环,并通过提出的机制解释了新形成的立体中心的非对映选择性引入。
Visible light triggered photo-decomposition of vinyl azides to (<i>E</i>)-stilbene derivatives <i>via</i> 1,2-acyl migration
photocatalyst-free visible light assisted synthetic route to various (E)-stilbene derivatives was developed. The reaction proceeds through a denitrogenative photo-decomposition of vinyl azides into 2H-azirines followed by neighboring amino group assisted ring opening, 1,2-acyl migration and enolization. The photochemical reaction offers light harvesting without any photocatalyst to access a wide variety of substituted
