We report the phosphine-catalyzed intermolecular carbofluorination of alkynes using acyl fluorides as fluorinating reagents. This reaction promises to be a useful method for the synthesis of highly substituted monofluoroalkene derivatives since acyl fluor
Three-step α-acylation of (E)-cinnamate esters with inversion of stereochemistry through formation and cleavage of carbon- pentamethylcyclopentadienyl bonds
Uemura, Minoru,Yorimitsu, Hideki,Oshima, Koichiro
, p. 408 - 409 (2007/10/03)
The reaction of cinnamate esters with lithium pentamethylcyclopentadienide in the presence of chlorodiethylaluminum provides the corresponding 1,4-adducts in high yield. The adducts undergo α-acylation reaction upon treatment with lithium diisopropylamide
STEREOCHEMISTRY OF AMINE-CATALYZED KNOEVENAGEL REACTIONS
Tanikaga, Rikuhei,Konya, Naoto,Kaji, Aritsune
, p. 1583 - 1586 (2007/10/02)
The amine-catalyzed Knoevenagel reactions of aldehydes and active methylene compounds containing two activating groups were found to involve many reversible steps, and the diastereomeric intermediary condensation compounds yielded thermodynamically stable products via carbanionic intermediates stablized and sterically affected by two activating groups.
