The rational design and implementation of enantiodivergent enamine catalysis is reported. A simple secondary amine catalyst, 2-methyl-l-proline, and its tetrabutylammonium salt function as an enantiodivergent catalyst pair delivering the enantiomers of α-functionalized aldehyde products in excellent enantioselectivities. This novel concept of designed enantiodivergence is applied to the enantioselective α-amination, aldol, and α-aminoxylation/α-hydroxyamination reactions of aldehydes.

Stereoselective alkylations of proline-based amino amides are described, where high levels of either a cis or trans configuration can be attained simply by the choice of the aminal group. Isobutryaldehyde-derived aminals provide the cis configuration, whi
The first enantioselective approach to 13a-methyl-14- hydroxyphenanthroindolizidine alkaloids - Synthetic studies towards hypoestestatin 2

The first enantioselective approach to 13a-methyl-14- hydroxyphenanthroindolizidine alkaloids was achieved in six linear steps from phenanthryl alcohol and features a highly substrate-dependent Parham cycloacylation and Seebach's enantioselective alkylation as the key steps. The route is concise, protecting-group free, provides access to all stereoisomers, and works on a gram scale. In addition to the putative structure of hypoestestatin 2, the other three stereoisomers and two structurally related analogues were synthesized, none of which shows identical NMR spectra to those reported for natural hypoestestatin 2, which indicates that further structure revision is required. By using Seebach's stereoselective alkylation and Parham cyclization as key steps, the first strategy for the synthesis of 14-hydroxy-13a-methylphenanthroindolizidine alkaloids was developed. The route is practical (six steps in 30 % overall yield) and adaptable for all stereoisomers. In addition, we demonstrate for the first time that the structure of hypoestestatin 2 was misassigned.

, p. 10018 - 10035 (2007/10/03)
The synthesis of ten proline-modified analogues of the neuroprotective tripeptide GPE is described. Five of the analogues incorporate a proline residue with a hydrophobic group at C-2 and two further analogues have this side chain locked into a spirolactam ring system. The pyrrolidine ring was also modified by replacing the γ-CH2 group with sulfur and/or incorporation of two methyl groups at C-5.
