[reaction: see text] Three one-pot methods for the conversion of aldehydes to homoallyl ethers catalyzed by Bi(OTf)(3).xH(2)O (1x4) have been developed. The one-pot synthesis of homoallyl ethers can be achieved either by in situ generation of the ace

Bismuth compounds in organic synthesis. Deprotection of ketoximes using bismuth bromide-bismuth triflate

Autor: Robert L. Kohaus, Joshua N. Arnold, Ram S. Mohan, Patrick D. Hayes

Publikováno v: Tetrahedron Letters. 44:9173-9175

Ketoximes undergo deprotection in CH 3 CN/acetone/H 2 O (3:6:1) in the presence of 20–40 mol% BiBr 3 /5 mol% Bi(OTf) 3 . Bismuth(III) salts are relatively non-toxic, insensitive to air and inexpensive. These features coupled with the use of a relat

Three one-pot methods for the conversion of aldehydes to homoallyl ethers catalyzed by Bi(OTf)3·xH2O (1 < x < 4) have been developed. The one-pot synthesis of homoallyl ethers can be achieved either by in situ generation of the acetal followed by it

Bismuth Compounds in Organic Synthesis. Bismuth Nitrate Catalyzed Chemoselective Synthesis of Acylals from Aromatic Aldehydes

Autor: Joshua N. Arnold, David H. Aggen, Patrick D. Hayes, Ram S. Mohan, Nathaniel J. Smoter

Publikováno v: ChemInform. 35

Aromatic aldehydes are smoothly converted into the corresponding acylals in good yields in the presence of 3–10 mol% Bi(NO3)3·5H2O. Ketones are not affected under the reaction conditions. The relatively non-toxic nature of the catalyst, its ease o
