Novel generation and cycloaddition of N-silylated azomethine ylides from α-silylimidates and trifluorosilane

, p. 12969 - 12976 (2007/10/03)
The Generation of N-silylated azomethine ylides was achieved by the reaction of α-silylimidates and trifluorophenylsilane. The generated azomethine ylides can be regarded as synthetic equivalents of nitrile ylides since they have an alkoxy group which may
Novel generation of azomethine ylide from N-(α-silylbenzyl)amide by silicon shift: An equivalent of nitrile ylide
Ohno,Komatsu,Miyata,Ohshiro
, p. 5813 - 5816 (2007/10/02)
Azomethine ylides were generated from N-(α-silylbenzyl)amides by thermal silicon shift to the oxygen and trapped with dipolarophiles to give the same products as those from the corresponding nitrile ylides via elimination of silanol.
Metallic Base-Induced Cycloadditions of N-(1-Cyanoalkyl)imines via N-Metalated Azomethine Ylides: Enhanced Reactivity and High Regio- and Stereoselectivity
Tsuge, Otohiko,Kanemasa, Shuji,Yorozu, Kiyotaka,Ueno, Kazunori
, p. 3359 - 3366 (2007/10/02)
Lithiation of N-(1-cyanoalkyl)imines with LDA generates new N-lithiated azomethine ylide 1,3-dipoles which show enhanced reactivity toward dipolarophiles.They undergo exclusively regio- and stereoselective 3+2 cycloaddition reaction with α,β-unsaturated e
Stereoselectivity of Cycloaddition of N-(Cyanomethyl)- and N-(α-Cyanobenzyl)imines with Olefinic Dipolarophiles. Synthetic Equivalents of Nitrile Ylide 1,3-Dipoles
Tsuge, Otohiko,Ueno, Kazunori,Kanemasa, Shuji,Yorozu, Kiyotaka
, p. 1809 - 1824 (2007/10/02)
N-(Cyanomethyl)- and N-(α-cyanobenzyl)imines derived from a variety of aldehydes and ketones can tautomerize into N-protonated azomethine ylides which undergo cycloadditions with olefinic dipolarophiles.These cycloadditions are often accompanied by the el
Benzylidene(cyano)benzylamine as a 1,3-Dipole
Tsuge, Otohiko,Ueno, Kazunori
, p. 1411 - 1414 (2007/10/02)
Benzylidene(cyano)benzylamine reacted as an azomethine ylide with DMAD and olefinic dipolarophiles.In most cases, however, the products derived from the initially formed cycloadducts with the elimination of hydrogen cyanide were obtained.
