[作者:BAO HONGLI; QI XIANGBING; TAMBAR UTTAM K,期刊:SYNLETT, 页码:1789-1792 , 文章类型: Article,,卷期:2011年-13]
- Despite the long history of [2,3]-sigmatropic rearrangements, there are surprisingly few catalytic and enantioselective variants of these transformations. This article describes the most common strategies developed for s...
- Allyl and Benzyl Dance under Basic Conditions
[作者:EL KAIM LAURENT; GRIMAUD LAURENCE; PURUMANDLA SRINIVAS REDDY,期刊:SYNLETT, 页码:1816-1820 , 文章类型: Article,,卷期:2011年-13]
- Ugi-Smiles adducts formed from allyl (propargyl or benzyl) amine rearrange under basic condition with an allyl migration between two nitrogen atoms. The shift is reversible and may be controlled by the strength of the ba...

- Reaction of the title substrate with methylhydrazine yields, via a domino process, HF elimination-beta-addition/elimination-cyclocondensation, to 3-hydroxy-5-trifluoromethylpyrazol-4-ylacetic acid derivatives. In a simil...
- Synthesis of cis-4,5-Diarylazepanes
[作者:CHANG MENGYANG; LEE NIENCHIA,期刊:SYNLETT, 页码:1875-1880 , 文章类型: Article,,卷期:2011年-13]
- Substituted cis-4,5-diarylazepanes are synthesized in modest overall yields starting from 5,5-diarylazepan-4-ones by a reduction, mesylation, rearrangement, and hydrogenation reaction sequence.
