  Target-oriented synthesis: miscellaneous synthetic routes to access 1,4-enediones through the coupling of 1,3-dicarbonyl compounds with multiform substrates

  摘要：

  Target-oriented synthetic protocol was presented for the synthesis of 1,4-enediones. The approach can efficiently construct 1,4-enediones through different reaction pathways from multiform substrates alpha-halo aromatic ketones, 2-hydroxy-aromatic ketones and methyl carbinols. In this reaction, CuI was found to be the most efficient catalyst. Multiform substrates were also found to perform well to afford the products in a one-pot fashion. (C) 2013 Elsevier Ltd.

• Carbon-13 NMR spectra of some 4-substituted phenacyl chlorides and iodides
  作者：Paulo Roberto Olivato、Sandra Alvarez Guerrero、Roberto Rittner

  DOI：10.1002/mrc.1260250218

  日期：1987.2

  The 13 NMR singles for some 4‐substituted phenacylchlorides and iodides were assigned. The carbonyl carbons exhibit upfield shifts compared with those of the corresponding 4‐substituted acetophenones; in the chlorinated derivatives a downfield shift is observed for the α‐methylene carbons, while a reverse effect occurs in the iodinated compounds. The chemical shifts of the aromatic ring carbons are

  指定了一些 4 取代苯甲酰氯和碘化物的 13 NMR 单峰。与相应的 4-取代苯乙酮相比，羰基碳表现出高场位移；在氯化衍生物中观察到α-亚甲基碳的低场位移，而在碘化化合物中发生相反的作用。芳环碳的化学位移与使用取代基化学位移计算的那些非常一致。

  representatives of this novel class of triazide compounds: Despite their high nitrogen content, the geminal triazides are easy to handle, even when preparative‐scale syntheses are performed. (Caution: These procedures still require protective measures!) The triazides are now broadly available for further studies regarding their properties and reactivity. Furthermore, we show how the method can be used to

  The hydration of haloalkynes to give α-halomethyl ketones was achieved based on a combination of a Cu(OAc)2 catalyst and a TFA (trifluoroacetic acid) promoter. This is the first synthesis of chloro/bromo/iodo methyl ketones through a hydration reaction catalyzed by a recyclable catalytic system. The catalytic system has a wide substrate scope and excellent chemoselectivity, and the procedure can also
