Accessing N-heteroarylated indoles and benzimidazoles from 2-alkynyl cyclohexadienimines and cyclohexadienones through metal-catalyzed tandem reactions [作者：YANG MIN; TANG JIE; FAN RENHUA,期刊：Chemical Communications, 页码：11775-11777 , 文章类型： Article，,卷期：2012年48-96] N-Indolyl or N-benzofuranyl indoles and benzimidazoles were prepared through metal-catalyzed tandem reactions between 2-alkynyl cyclohexadienimines or cyclohexadienones and 2-alkynylanilines or N-1-benzylbenzene-1,2-diam... Poly(ethylene glycol) as reaction medium for mild Mizoroki-Heck reaction in a ball-mill [作者：DECLERCK VALERIE; COLACINO EVELINA; BANTREIL XAVIER; MARTINEZ JEAN; LAMATY FREDERIC,期刊：Chemical Communications, 页码：11778-11780 , 文章类型： Article，,卷期：2012年48-96] Phosphine-free palladium-catalyzed Mizoroki-Heck reaction was performed using ball-milling in polyethylene glycol under mild conditions. Good to excellent yields of coupling products were obtained. This activation techni... Mechanosynthesis of amides in the total absence of organic solvent from reaction to product recovery [作者：METRO THOMASXAVIER; BONNAMOUR JULIEN; REIDON THOMAS; SARPOULET JORDI; MARTINEZ JEAN; LAMATY FREDERIC,期刊：Chemical Communications, 页码：11781-11783 , 文章类型： Article，,卷期：2012年48-96] The synthesis of various amides has been realised avoiding the use of any organic solvent from activation of carboxylic acids with CDI to isolation of the amides. Mechanochemistry was the key point of the process allowin... Lewis acid-catalyzed unexpected selective C-C bond cleavage: an efficient and mild construction of cyclopentenes [作者：YU QIONG; MA SHENGMING,期刊：Chemical Communications, 页码：11784-11786 , 文章类型： Article，,卷期：2012年48-96] An intriguing Lewis acid-catalyzed intramolecular ring-opening/cyclization reaction of cyclopropylvinylallenes is developed. This process proceeds at ambient temperature to afford the structurally diverse cyclopentenes e... A method for the synthesis of pyridines from aldehydes, alkynes and NH4OAc involving Rh-catalyzed hydroacylation and N-annulation [作者：SIM YONGKYUN; LEE HYEJEONG; PARK JUNGWOO; KIM DONGSU; JUN CHULHO,期刊：Chemical Communications, 页码：11787-11789 , 文章类型： Article，,卷期：2012年48-96] A new method for regiocontrolled pyridine synthesis has been developed involving sequential Rh(I)-catalyzed chelation-assisted hydroacylation of alkynes with aldehydes followed by Rh(III)-promoted N-annulation of the res... Calcium amido-bisoxazoline complexes in asymmetric hydroamination/cyclisation catalysis [作者：NIXON TRACY D; WARD BENJAMIN D,期刊：Chemical Communications, 页码：11790-11792 , 文章类型： Article，,卷期：2012年48-96] Calcium complexes bearing bis(oxazolinylphenyl)amine (BOPA) ligands have been prepared, and their redistribution chemistry studied. The complexes [Ca(R-BOPA){N(SiMe3)(2)}(THF)] (R = Pr-i 1a, Ph 1b and Bn 1c) are active i... Iridium(III) azuliporphyrins [作者：LASH TIMOTHY D; POKHAREL KOMAL; ZELLER MATTHIAS; FERRENCE GREGORY M,期刊：Chemical Communications, 页码：11793-11795 , 文章类型： Article，,卷期：2012年48-96] Azuliporphyrins were reacted with [Ir(COD)Cl](2) in refluxing o- or p-xylene to give novel iridium(III) derivatives that regioselectively incorporated an oxidized solvent molecule. The iridium(III) is inserted within the... A concise synthesis of 3-aroylflavones via Lewis base 9-azajulolidine-catalyzed tandem acyl transfer-cyclization [作者：YOSHIDA MASAHITO; SAITO KOYA; FUJINO YUTA; DOI TAKAYUKI,期刊：Chemical Communications, 页码：11796-11798 , 文章类型： Article，,卷期：2012年48-96] Lewis base-catalyzed tandem acyl transfer-cyclization of acylated o-alkynoylphenols leading to 3-aroylflavones was developed. 9-Azajulolidine smoothly promoted the reaction of the aroyl derivatives at ambient temperature...
