- Step-Efficient Access to Chiral Primary Amines
[作者:NUGENT THOMAS C; MARINOVA SOFIYA M,期刊:Synthesis, 页码:153-166 , 文章类型: Article,,卷期:2013年45-2]
- Routes to enantioenriched amines are outlined that employ reductive amination and carbanion addition methods. The strategies require either one or two reaction steps from prochiral carbonyl compounds for the synthesis of...
- An Expedient Access to Still-Gennari Phosphonates
[作者:MESSIK FRAUKE; OBERTHUER MARKUS,期刊:Synthesis, 页码:167-170 , 文章类型: Article,,卷期:2013年45-2]
- An inexpensive and efficient route to the Still-Gennari phosphonates, methyl and ethyl bis(2,2,2-trifluoroethyl)phosphonoacetates, has been developed. This short reaction sequence is operationally simple and makes these ...
- A Reliable Synthesis of 3-Amino-5-Alkyl and 5-Amino-3-Alkyl Isoxazoles
[作者:JOHNSON LELAND; POWERS JAMES; MA FUPENG; JENDZA KEITH; WANG BING; MEREDITH ERIK; MAINOLFI NELLO,期刊:Synthesis, 页码:171-173 , 文章类型: Article,,卷期:2013年45-2]
- A reliable procedure that can be used to access a wide range of 3-amino-5-alkyl and 5-amino-3-alkyl isoxazoles was developed. Reaction temperature and pH were key factors that determined the regioselectivity of the two r...
- Solvent-Free Preparation of N,N '-Dialkylbenzenediamines
[作者:KUO HSINYA; LIAO BEISIH; LIU SHIUHTZUNG,期刊:Synthesis, 页码:189-192 , 文章类型: Article,,卷期:2013年45-2]
- A diiridium complex, stabilized by a bis(N-heterocyclic carbene) ligand, was found to be an effective precatalyst for the N,N'-dialkylation of o-, m-, and p-benzenediamine in excellent yields. Benzyl and primary aliphati...
- Synthesis of 1-Amino-2,5-dihydro-1H-phosphole 1-Oxides and Their N-Phosphinoyl Derivatives, Bis(2,5-dihydro-1H-phosphol-1-yl)amine P,P '-Dioxides
[作者:KISS NORA ZSUZSA; SIMON ANDRAS; DRAHOS LASZLO; HUBEN KRZYSZTOF; JANKOWSKI STEFAN; KEGLEVICH GYOERGY,期刊:Synthesis, 页码:199-204 , 文章类型: Article,,卷期:2013年45-2]
- Depending on the molar ratio of the reactants and on the order of mixing, the reactions of a series of primary amines with 1-chloro-2,5-dihydro-1H-phosphole 1-oxides prepared in situ from the corresponding hydroxy-dihydr...
- Studies toward the Total Synthesis of Carolacton
[作者:SABITHA GOWRAVARAM; SHANKARAIAH K; PRASAD M NAGENDRA; YADAV JHILLU S,期刊:Synthesis, 页码:251-259 , 文章类型: Article,,卷期:2013年45-2]
- An efficient synthesis of the C1-C19 segment of carolacton is described, starting from D-ribose, (-)-beta-citronellene and a homopropargylic alcohol, and which employs a Nozaki-Hiyama-Kishi (NHK) coupling as the key step...
