| Abstract |
|
|
|
| Potassium phenylethynyltrifluoroborate and potassium styryltrifluoroborates react with alpha, alpha-dichlorinated aldimines in the presence of BF(3). OEt(2) as a Lewis acid to give a new stable class of functionalized propargylamines and allylamines. The use of hexafluoroisopropanol as a co-solvent in this modified Petasis reaction allows high yield isolation of the target compounds. (C) 2007 Elsevier Ltd. All rights reserved. | |
