The Mukaiyama aldol type condensation of t-butyldimethylsilyloxypyrrole 1b with methyl 2-formylbenzoate furnished the aldol adduct 9 with high yield and complete stereoselectivity. An erythro (anti) configuration was established (X-ray) in sharp cont

A Yb(OTf)3-catalyzed Mannich-type reaction of the chiral non-racemic silyloxypyrrole 2 is described. The three-component (silyloxypyrrole, aldehyde and amine) reaction allowed the use of aromatic as well as aliphatic enolisable aldehydes. The erythro

The one-pot three-component vinylogous Mannich reaction of trialkylsilyloxyfurans with anilines and aldehydes in the presence of catalytic amounts of Yb(OTf) 3 gave the substituted aminoalkyl-butenolides in good yields (>90 %) and diastereoselectivit
