An organocatalytic enantioselective aldol reaction using paraformaldehyde as the C1-unit has been developed for the synthesis of 2-oxindoles sharing vicinal all-carbon quaternary stereocenters. The methodol. is eventually employed in the formal total synthesis of (+)-folicanthine (I).
Journal of Organic Chemistry published new progress about Aldol addition catalysts, stereoselective. 152140-65-3 belongs to class chiral-phosphine-ligands, and the molecular formula is C54H42N2O2P2, Name: N,N’-(11R,12R)-(9,10-Dihydro-9,10-ethanoanthracene-11,12-diyl)bis[2-(diphenylphosphino)benzamide].
