  Sunlight-Driven Forging of Amide/Ester Bonds from Three Independent Components: An Approach to Carbamates

  摘要：

  A photoredox catalytic route to carbamates enabled by visible irradiation (or simply sunlight) has been developed. This process leads to a novel approach to the construction of heterocyclic rings wherein the amide or ester motifs of carbamates were assembled from three isolated components. Large-scale experiments were realized by employing continuous flow techniques, and reuse of photocatalyst demonstrated the green and sustainable aspects of this method.

  1-benzoxazines via formation of tetrafluoroborates. The substitution of halogen in 2-(α-haloalkyl)-4,4-diphenyl-4H-3,1-benzoxazines by NH and SH nucleophiles was performed. The effect of electrophilic substitution in the annelated aromatic ring in a series of 2,4-substituted 4H-3,1-benzoxazines has been studied.

  late-stage [11C], [13C] and [14C]carbon isotope labeling of cyclic carbamates is reported. This protocol allows the incorporation of carbon dioxide, the primary source of carbon-14 and carbon-11 radioisotopes, in a direct, cost-effective and sustainable manner. A disconnection/reconnection strategy, involving ring opening/isotopic closure, was also implemented.

  Addition of organometallics to N-(α-haloacyl)-o-aminobenzonitrile resulted in the formation of 2,5-disubstituted 1,4-benzodiazepin-3-ones, whereas N-(β-haloacyl)-o-aminobenzonitrile gave 2,6-disubstituted 1,5-benzodiazocin-4-ones under similar conditions. Initial cylization of N-(β-haloacyl)-o-aminobenzonitrile to obtain the corresponding lactam (e.g.α,α-dimethyl-N-(2-cyanophenyl)-β-lactam) increased the yield of 1,5-benzodiazocin-4-ones significantly. Somewhat surprisingly, addition of lithium reagents to N-(β-haloacyl)-o-aminobenzonitrile gave 4,4-disubstituted quinazolines viaGrob fragmentation.

  向N-(α-卤代酰基)-邻氨基苯甲腈中添加有机金属化合物，可形成2,5-二取代的1,4-苯并二氮平-3-酮，而在类似条件下，向N-(β-卤代酰基)-邻氨基苯甲腈中添加则得到2,6-二取代的1,5-苯并二氮杂环-4-酮。初步环化N-(β-卤代酰基)-邻氨基苯甲腈以获得相应的内酰胺（例如α,α-二甲基-N-(2-氰基苯基)-β-内酰胺）显著提高了1,5-苯并二氮杂环-4-酮的产率。稍微出人意料的是，向N-(β-卤代酰基)-邻氨基苯甲腈中添加锂试剂通过Grob碎片化反应得到了4,4-二取代的喹唑啉。

  Oxygenation of cyclic diphenyl iodoniums (CDPIs) with varied medium‐ring sizes has been fully investigated. This practical copper‐catalyzed tandem reaction of CDPIs with water as the oxygen source enables the construction of derivatised dibenzofurans and xanthenes at moderate to good yields. Moreover, structurally important xanthones are also successfully accessed under the oxygenation conditions with

  activation under gold(I) catalysis was developed. The scope of the protocol was determined by synthesizing some electron-neutral, electron-poor as well as electron-rich derivatives including the dibenzofurane and carbazole heterocycles. The mechanism of this reaction was elucidated by theoretical calculations using a ONIOM(M08-HX/mixed-basis:PM6) hybrid scheme. Thereby we found a pericyclic transformation

  开发了一种在金（I）催化下通过直接C sp 3 -H活化合成茚满的催化，实用且高产的方法。通过合成一些电子中性，贫电子以及富电子衍生物（包括二苯并呋喃和咔唑杂环）来确定方案的范围。通过使用ONIOM（M08-HX / mixed-basis：PM6）混合方案的理论计算阐明了该反应的机理。因此，我们发现了一个涉及[1,5] -H移位的周环转变，生成了金（I）-卡宾，并演化为茚衍生物。与一些报告相比，我们的协议提出了C sp 3 -H键的直接激活。
