One-pot Synthesis of 2, 5-Disubstituted Oxazoles Using Poly[styrene（iodosodiacetate）]

2,5-Disubstituted oxazoles were prepared conveniently by treatment of aromatic α-methyl ketones and nitriles with poly[styrene(iodosodiacetate)] in one-pot process.     

The First Intramolecular Charge Transfer Transition Based on 2-Ureido-4[1H]-pyrimidinone Binding Module

The first intramolecular charge transfer transition based on 2-ureido-4[1H]-pyrimidinone binding module was reported.     

Solid Phase Synthesis of 2-Substituted 1,3-Oxazin-6-ones Using Resin-bound Cyclic Malonic Acid Ester

A facile solid phase synthesis of 2-substituted 1,3-oxazin-6-ones using polymer-supported Meldrum‘s acid has been reported. Reaction of the resin-bound cyclic malonic acid ester with triethyl orthoformate and subsequent double substitution with amide, afforded the corresponding polymer-supported acylaminomethylene cyclic malonic acid ester, which upon thermal treatment led to 1, 3-oxazin-6-ones in good yields and with high purity.

无介质微波作用下酮与稳定叶立德的反应

酮与稳定膦叶立德在家用微波炉中加热，在无任何溶剂或固体介质条件下，4．5min之内完成反应，得到了良好产率的Wittig反应产物，较之液相苯中回流反应的传统方法，此法具有时间短、操作步骤简单、无毒害等优点，同时使一些在传统方法中与稳定叶立德不反应或难反应的酮得以进行并有较好收率。此外，在得到α，β-不饱和酯的同时，还发现了少量重排产物β，γ-不饱和酯，并对其机理进行了推测与证明。
