All the sy... One-Pot, Three-Step Copper-Catalyzed Five-/Four-Component Reaction Constructs Polysubstituted Oxa(Thia)zolidin-2-imines [作者：MADAAN CHETNA; SARAF SHUDDHAM; PRIYADARSHANI GARIMA; REDDY P PURUSHOTHAM; GUCHHAIT SANKAR K; KUNWAR A C; SRIDHAR B,期刊：SYNLETT, 页码：1955-1959 , 文章类型： Article，,卷期：2012年-13] A novel one-pot synthesis of polysubstituted oxa(thia)zolidin-2-imines has been developed. It employs A(3)-coupling of aldehyde and amine with alkyne to form propargyl amine, which on (thio) amidation with iso(thio)cyana... W(CO)(5)(L)-Catalyzed Cyclization of alpha-Alkynyl-beta-dicarbonyl Derivatives: Synthesis of Methylenelactones, Furans, and Methylenecyclopentanes [作者：MENG XIANGJIAN; KIM SUNGGAK,期刊：SYNLETT, 页码：1960-1964 , 文章类型： Article，,卷期：2012年-13] W(CO)(5)(L)-Catalyzed cyclization of alpha-alkynyl-beta-keto acids, keto esters, and diketones provides methylenelactones, furans, and methylenecyclopentanes via 5-exo-dig cyclization. Also, the present approach can be f... Novel Method for the Synthesis of alpha-Amino-alpha '-hydroxyalkylphosphinic Acids and Bis(alpha-aminoalkyl)phosphinic Acids: Nuclephilic Addition of alpha-Hydroxy-H-phosphinic Acids to Diimines [作者：KABOUDIN BABAK; HAGHIGHAT HAMIDEH; ALAIE SAIED; YOKOMATSU TSUTOMU,期刊：SYNLETT, 页码：1965-1969 , 文章类型： Article，,卷期：2012年-13] We report here a novel and simple method for the synthesis of alpha-amino-alpha'-hydroxyalkylphosphinic acids in good yields in two simple steps without any protection-deprotection steps. We have developed an efficient m... A Novel Strategy for the Construction of Azole Heterocycles via an Oxidative Desulfurization Approach Using Iodobenzene and Oxone (R) [作者：PATEL KAVITKUMAR N; JADHAV NIKHIL C; JAGADHANE PRASHANT B; TELVEKAR VIKAS N,期刊：SYNLETT, 页码：1970-1972 , 文章类型： Article，,卷期：2012年-13] The oxidative desulfurization approach has been utilized for the construction of oxadiazole and thiadiazole heterocycles using iodobenzene and Oxone (R). The use of iodobenzene and the inexpensive readily available oxida...
