• Microwave-assisted regioselective olefinations of cyclic mono- and di-ketones with a stabilized phosphorus ylide

  4-cyclohexanediones with the ylide at 190 °C for 20 min in MeCN afforded the exocyclic olefins in >94:6 isomer ratios. On the other hand, the same reactions carried out at 230 °C for 20 min in the presence of 20 mol % DBU furnished the endocyclic olefins in >83:17 isomer ratios. The base-mediated isomerization of the exocyclic olefins into the endocyclic isomers was primarily driven by thermodynamic stability of the

  在控制的微波加热下，许多环状的单酮和二酮与（carbethoxyethidene）三苯基磷芳烷进行区域选择性烯烃化反应。4-取代的环己酮或1,2-和1,4-环己二酮与ylide在MeCN中在190°C下进行Wittig反应20分钟，得到的外环烯烃的异构体比率> 94：6。另一方面，在20mol％DBU的存在下在230℃下进行20分钟的相同反应提供了＞ 83:17异构体比率的内环烯烃。碱介导的环外烯烃异构化成环内异构体主要是由产物的热力学稳定性驱动的，并且研​​究了环结构对去共轭作用的影响。

  A facile synthetic approach to β,γ-unsaturated esters by deconjugative esterification of α,β-unsaturated carboxylic acids with alcohols in the presence of 1,3-dicyclohexylcarbodiimide (DCC), Me3N·HCl, and Me2NEt is described. The one-pot synthesis was effectively improved under microwave irradiation.

  一种简便的合成方法，通过在1,3-二环己基氨基脲（DCC）、氯化三甲胺（Me3N·HCl）和二乙基氨（Me2NEt）的存在下，将α,β-不饱和羧酸与醇进行脱共轭醇酯化，合成β,γ-不饱和酯。这种一步法合成在微波辐射下得到了有效改善。

  4-(Pyrrolidin-1-yl)pyridine-catalyzed deconjugative esterification of 2-cyclohexylideneacetic acids afforded isopropyl 2-(cyclohex-1-enyl)acetate by employing 1-ethyl-3-(3-dimethylaminopropyl)carbodiimide hydrochloride as a coupling reagent. On the other hand, 4-(pyrrolidin-1-yl)pyridine-catalyzed esterification with 1,3-dicyclohexylcarbodiimide was not accompanied by deconjugation and gave isopropyl 2-cyclohexylideneacetate.

• Highly regioselective Wittig reactions of cyclic ketones with a stabilized phosphorus ylide under controlled microwave heating

  Significant base and temperature effects on the Wittig reactions of cyclohexanones with (carbethoxymethylene)triphenylphosphorane under microwave irradiation were observed. For the Wittig reactions carried out in a domestic microwave oven under solvent-free conditions, the initially formed exo-olefin products isomerized into the thermodynamically more stable endo-olefins due to uncontrolled high reaction temperature. In sharp contrast, under controlled microwave heating, both exo- and endo-olefins have been selectively synthesized by accurately regulating the reaction temperature with or without a base.
