[作者:HEHN JOERG P; GAMBASANCHEZ DIEGO; KEMMLER MICHAEL; FLECK MARTIN; BASLER BIRTE; BACH THORSTEN,期刊:Synthesis, 页码:2308-2312 , 文章类型: Article,,卷期:2010年-13]
- Tetronic acid esters and amides, which are readily available from the corresponding tetronic acids, serve as useful starting materials in an intra-or intermolecular [2+2]-photocycloaddition reaction. Typical reaction con...
- Easier Preparation of 2,6-Di-tert-butylphenyl Derivatives
[作者:KNORR RUDOLF; ROSSMANN EVA CHRISTINE; KNITTL MONIKA,期刊:Synthesis, 页码:2124-2128 , 文章类型: Article,,卷期:2010年-13]
- Despite steric shielding by the 2,6-di-tert-butylphenyl group ('super-2,6-xylyl' = xyl*), inexpensive sodium phenolate (xyl*-ONa) reacts with dimethyl sulfate to produce only xyl*-OCH3 (94%) with complete suppression of ...
