Stereocontrolled conversion of 3-unsubstituted isoxazole compounds into Z-β-siloxyacrylonitriles. A new method for the regioselective synthesis of β-enaminoketones
Gonzalez,Gonzalez,Pulido
, p. 1005 - 1014 (2007/10/02)
The stereoselective synthesis of Z-β-siloxyacrylonitriles via base-induced ring cleavage of isoxazole precursors is described. Z-β-siloxyacrylonitriles react with organolithium compounds to give high yields of β-enaminoketones 1.

, p. 2027 - 2030 (2007/10/02)
A general method for the synthesis of Z-β-siloxyacrylonitriles from isoxazoles is reported.Their dienophilic activity is also described.
SYNTHESIS AND REARRANGEMENT OF CYCLOADDUCTS FROM TRIMETHYLSILANECARBONITRILE OXIDE
Sarlo, Francesco De,Brandi, Alberto,Goti, Andrea,Guarna, Antonio,Rovero, Paolo
, p. 511 - 518 (2007/10/02)
The cycloadducts from trimethylsilanecarbonitrile oxide and ethylenic or acetylenic compounds easily rearrange to open-chain intermediates, which, in turn, are hydrolysed respectively to β-hydroxynitriles and β-oxonitriles.The cycloadducts of the same nitrile oxide with sulfur dioxide and sulfinylamines are unstable, too, leading respectively to trimethylsilylisocyanate and trimethylsilylcarbodiimides.All these reactions are of preparative interest, in comparison with previous methods.
