Enantioselective hydrosilylations of the 3,4-dihydropyrrole derivatives 1a-c and 5 with in-situ catalysts consisting of [Rh(cod)Cl]2 and optically active phosphines yield the N-silyl compounds 2a-c and 6 in up to 66.1 % ee. The N-silyl derivatives were treated with acetic formic anhydride or trifluoroacetic anhydride to give the N-formyl and N-trifluoroacetyl compounds 3a-c, 4a-c, 7, and 8. The ...
