  A novel photochemical ring-contraction reaction of 5-unsubstituted 3, 1-benzoxazepines and their 5-halogeno or carboxyl derivatives to yield 3-formylindoles in an aprotic solvent is reported. This ring contraction was successfully extended to oxazepines having an alkoxycarbonyl function at the 5-position to give the indoles having this function at the 3-position. Though most of the oxazepines underwent the ring-contraction reaction only on irradiation at 254 nm, 5-carboxy derivatives or their esters afforded the ring-contraction products even at ≥ 300 nm. The intermediacy of 3H-indole species in these photochemical ring-contraction reactions was demonstrated by the isolation of methyl 3-acetyl-2-phenyl-3H-indole-3-carboxylate during the photolysis of methyl 4-methyl-2-phenyl-3, 1-benzoxazepine-5-carboxylate. It was found that this 3H-indole afforded methyl 6-and 4-acetyl-2-phenyl-indole-3-carboxylates upon further irradiation. The mechanism of this acetyl migration is discussed based on the result of the photochemical acetyl migration of methyl 1-acetyl-2-phenylindole-3-carboxylate.

  报道了一种在非质子溶剂中，5-未取代的3,1-苯并噁嗪和其5-卤素或羧基衍生物发生的新型光化学环收缩反应，生成3-甲酰基吲哚。这种环收缩反应成功扩展到5-位具有烷氧羰基功能的噁嗪，生成3-位具有该功能的吲哚。尽管大多数噁嗪仅在254 nm波长下发生环收缩反应，5-羧基衍生物或其酯甚至在≥ 300 nm波长下也能生成环收缩产物。通过在4-甲基-2-苯基-3,1-苯并噁嗪-5-羧酸甲酯的光解过程中分离出甲基3-乙酰基-2-苯基-3H-吲哚-3-羧酸酯，证明了这些光化学环收缩反应中3H-吲哚的中间体性质。发现进一步的辐照使这种3H-吲哚生成甲基6-和4-乙酰基-2-苯基-吲哚-3-羧酸酯。根据甲基1-乙酰基-2-苯基吲哚-3-羧酸酯的光化学乙酰迁移结果，讨论了这种乙酰迁移的机制。

Moreover, we discovered that a large variety of aliphatic amine N-oxides can easily be deoxygenated by using only phenylsilane. These practically simple approaches proceed well under metal-free conditions, tolerate many functionalities and are highly chemoselective. Combined experimental

  the most useful tools for synthesizing various N-heterocyclic compounds, the highly chemoselective deoxygenation of densely functionalized N-heterocyclic N-oxides has received much attention from the synthetic chemistry community. Here, we provide a protocol for the highly chemoselective deoxygenation of various functionalized N-oxides under visible light-mediated photoredox conditions with Na2-eosin

  由于它们的位点选择性C–H官能化现在被认为是合成各种N-杂环化合物的最有用的工具之一，因此稠密官能化的N-杂环N-氧化物的高度化学选择性脱氧受到了合成化学界的广泛关注。在这里，我们提供了一种在Na 2-曙红Y作为有机光催化剂的情况下，在可见光介导的光氧化还原条件下，对各种功能化N-氧化物进行高度化学选择性脱氧的方案。机理研究表明，有机光催化剂的激发态被Hantzsch酯还原性淬灭。这种操作简单的技术可耐受各种官能团，并允许高产率，数克级的脱氧。

  Conformationally restricted, spatially defined 12-30 membered macrocyclic ring systems of type (I) are constituted by three distinct building blocks: an aromatic template a, a conformation modulator b and a spacer moiety c as detailed in the description and the claims. Macrocycles of type (I) are readily manufactured by parallel synthesis or combinatorial chemistry. They are designed to interact with specific biological targets. In particular, they show agonistic or antagonistic activity on the motilin receptor (MR receptor), on the serotonin receptor of subtype 5-HT2B (5-HT2B receptor), and on the prostaglandin F2 • receptor (FP receptor). They are thus potentially useful for the treatment of hypomotility disorders of the gastrointestinal tract such as diabetic gastroparesis and constipation type irritable bowl syndrome; of CNS related diseases like migraine, schizophrenia, psychosis or depression; of ocular hypertension such as associated with glaucoma and preterm labour.

  Conformationally restricted, spatially defined 12-30 membered macrocyclic ring systems of formulae Ia and Ib are constituted by three distinct molecular parts: Template A, conformation Modulator B and Bridge C. These macrocycles Ia and Ib are readily manufactured by parallel synthesis or combinatorial chemistry in solution or on solid phase. They are designed to interact with a variety of specific biological target classes, examples being the agonistic or antagonistic activity on G-protein coupled receptors (GPCRs), ion channels and signal transduction pathways. In particular, these macrocycles act as antagonists of the motilin receptor, the FP receptor and the purinergic receptors P2Y 1 , as modulators of the serotonin receptor of subtype 5-HT 2B , as blockers of the voltage-gated potassium channel K v 1.3 and as inhibitors of the β-catenin-dependent “canonical” Wnt pathway. Thus they are showing great potential as medicaments for a variety of diseases.
