The use of highly reactive, transient intermediates In this MCMR permits short reaction times, even at ... Total Synthesis of (-)-Leuconicine A and B [作者：SIRASANI GOPAL; ANDRADE RODRIGO B,期刊：Organic Letters, 页码：4736-4737 , 文章类型： Article，,卷期：2011年13-17] Concise asymmetric total syntheses of Strychnos alkaloids (-)-leuconicine A (14 steps, 9% overall yield) and B (13 steps, 10% overall yield) have been accomplished. Key steps include (1) our sequential one-pot spiro-cycl... Catalytic, Asymmetric Hypervinylogous Mukaiyama Aldol Reactions of Extended Furan-Based Silyl Enolates [作者：CURTI CLAUDIO; BATTISTINI LUCIA; SARTORI ANDREA; LODOLA ALESSIO; MOR MARCO; RASSU GLORIA; PELOSI GIORGIO; ZANARDI FRANCA; CASIRAGHI GIOVANNI,期刊：Organic Letters, 页码：4738-4741 , 文章类型： Article，,卷期：2011年13-17] Virtually perfect transmittal of the enolate reactivity up to five conjugated double bonds from the origin allows a series of furan-based silyloxypolyenes to add to aldehyde carbonyls at the most distant point of the mol... Diporphyrinylamines: Synthesis and Electrochemistry [作者：PEREIRA ANA M V M; NEVES MARIA G P M S; CAVALEIRO JOSE A S; JEANDON CHRISTOPHE; GISSELBRECHT JEANPAUL; CHOUA SYLVIE; RUPPERT ROMAIN,期刊：Organic Letters, 页码：4742-4745 , 文章类型： Article，,卷期：2011年13-17] The synthesis of three possible diporphyrinylamines is described. All compounds were obtained by using the Buchwald-Hartwig aromatic amination reaction. The electronic spectra of the three porphyrin dimers showed charact... Scalable Synthesis of 1-Bicyclo[1.1.1]pentylamine via a Hydrohydrazination Reaction [作者：BUNKER KEVIN D; SACH NEAL W; HUANG QINHUA; RICHARDSON PAUL F,期刊：Organic Letters, 页码：4746-4748 , 文章类型： Article，,卷期：2011年13-17] The reaction of [1.1.1]propellane with di-tert-butyl azodicarboxylate and phenylsliane In the presence of Mn(dpm)(3) to give di-tert-butyl 1-(bicyclo[1.1.1]pentan-1-yl)hydrazine-1,2-dicarboxylate Is described. Subsequent... Tandem Reactions of 1,2,4-Oxadiazoles with Allylamines [作者：PICCIONELLO ANTONIO PALUMBO; PACE ANDREA; BUSCEMI SILVESTRE,期刊：Organic Letters, 页码：4749-4751 , 文章类型： Article，,卷期：2011年13-17] A reaction of 3-chloro-1,2,4-oxadiazoles with allyiamine and diallyiamine has been investigated. 3,3a,4,5-Tetrahydrolsoxazolo[3,4-d]pyrimidines are produced through a tandem ANRORC/[3 + 2]cycloaddition pathway consisting... Pentafluorophenylhalocarbenes [作者：MOSS ROBERT A; SHEN YONGMAIO; WANG LEI; KROGHJESPERSEN KARSTEN,期刊：Organic Letters, 页码：4752-4754 , 文章类型： Article，,卷期：2011年13-17] Pentafluorophenylchlorocarbene and pentafluorophenylfluorocarbene are highly reactive species and effective carriers of fluorine labels via addition to alkenes and insertion into C-H bonds.
