  叔丁基过氧化物的重排用于建设多取代呋喃

  摘要：

  布朗斯台德酸催化的叔丁基过氧化物的重排提供了一种新的策略，可通过1,2-芳基迁移来构建2,3-二取代的呋喃。此外，叔丁基过氧化物也可以通过一系列碱催化的Kornblum-DelaMare重排和酸促进的Paal-Knorr反应转化为2,3,5-三取代或2,5-二取代的呋喃。

  convenient method for the one-pot synthesis of furans from β-keto esters and α-halo ketones was developed using an acid- and base-supported reagent system ‘Na2CO3/Al2O3-PPA/SiO2’. The condensation reaction of triketones, which are formed from the reaction of β-keto esters with α-halo ketones in the presence of Na2CO3/Al2O3, was promoted by PPA/SiO2 to give the corresponding furans in good yields. This method

  Polysubstituted furans were obtained with excellent yields via the electrophilic alkynylation of 1,3‐dicarbonyl compoundsws with phenyl‐ or ester‐substituted brominated alkynes. The reaction is catalyzed by the inexpensive and readily available catalyst, cobalt(II) chloride, and has a wide substrate scope. The C(sp)C(sp3) coupling occurs under mild conditions with short reaction times and does not

  多取代呋喃是通过1,3-二羰基化合物ws与苯基或酯取代的溴代炔烃的亲电炔基化而获得的，具有优异的收率。该反应由廉价且容易获得的催化剂氯化钴（II）催化，并且具有广泛的底物范围。C（sp）C（sp 3）偶联在温和的条件下发生，反应时间短，不需要惰性气氛或配体。建议反应通过钴（II）与去质子化的1,3-二羰基化合物的螯合配合物进行。

  An efficient protocol for the synthesis of furans through Rh(III)-catalyzed vinyl C–H activation from acrylic acids and α-diazocarbonyl compounds has been developed. The reaction features broad functional group tolerance and affords a series of furans in moderate to good yields. Moreover, no additives such as copper or silver salts are required. Some control experiments are performed to give insight

  A novel silver-mediated highly selective oxidative C-H/C-H functionalization of 1,3-dicarbonyl compounds with terminal alkynes for the creation of polysubstituted furans and pyrroles in one step has been demonstrated. Promoted by the crucial silver species, perfect selectivity and good to excellent yields could be achieved. This protocol represents an extremely simple and atom-economic way to construct polysubstituted furans and pyrroles from basic starting materials under mild conditions.
