Lipase-mediated kinetic resolution of cis-1,2-indandiol and the Ritter reaction of its mono-acetate

Lipase-mediated kinetic resolution of cis-1,2-indandiol 5 in the presence of lipase PS was examined. Enantiomerically enriched (1S,2R)-2-acetoxy-1-indanol 6a was obtained when cis-1,2-indandiol 5 was treated with one equivalent of vinyl acetate. Treatment of 5 with two equivalents of vinyl acetate furnished a mixture of (1R,2S)-2-acetoxy-1-indanol 6a and (1R,2S)-1-acetoxy-2-indanol 6b. A route to both enantiomers of 1 was also developed by using the enantiomerically enriched mono-acetate thus obtained.

Highly stereoselective reduction of alpha-keto esters: Utility of cis-1-arylsulfonamido-2-indanols as chiral auxiliaries

The reduction of alpha-keto esters bearing cis-1-arylsulfonamide-2-indanol derivatives proceeded with high diastereoselectivities providing the corresponding alpha-hydroxy esters in excellent yields. The chiral auxiliary group is removed under mild basic conditions and recovered.

Solid phase assisted synthesis of HIV-1 inhibitors. Expedient entry to unsymmetrical substitution of a C2 symmetric template

A solid phase synthesis has been developed leading up to unsymmetrical HIV-1 protease inhibitors that are not readily available by conventional solution phase chemistry (18a-g). To prepare these compounds the hydroxyl group of (1s,2r)-(-)-cis-1-phthalimido-2-indanol (3) was coupled to a Merrifield resin via a dihydropyrane linker. Cleavage of the phthalimido protecting group and reaction of the liberated amine with the bis-activated symmetrical diacid 15 resulted in the resin bound amide 16. Coupling of 16 with amino acids and amines followed by hydrolysis produced the desired unsymmetrical products 18a-g from which potent HIV-1 protease inhibitors were identified, e.g., 18e (k(i) = 0.1 nM), 18a (k(i) = 0.2 nM) and 18c (k(i) = 2 nM).

Multifunctional isoquinoline-oxazoline ligands of chemical and biological importance

Multifunctional isoquinoline-oxazolines (MIQOXs) were conceived and synthesized from commercially available chiral amino acids. The multifunctional role of MIQOXs was demonstrated by Pd-catalyzed highly enantioselective addition of arylboronic acids to nitrostyrenes, and by the discovery of novel antifungal candidates.

Water versus solvent-free conditions for the enantioselective inter- and intramolecular aldol reaction employing l-prolinamides and l-prolinethioamides as organocatalysts

Organocatalysts 1, derived from L-proline and (1S,2R)-cis-l-aminoindan-2-ol or (R)-l-aminoin-dane, are evaluated as promoters in the direct asymmetric aldol reaction between ketones and aromatic aldehydes in the presence of water and under solvent-free reaction conditions. L-Prolinethioamides 1c and 1d exhibited higher enantioselectivity than the corresponding prolinamides 1a and 1b in the model aldol reaction between cyclohexanone and 4-nitro-benzaldehyde in the presence of 4-nitrobenzoic acid as cocatalyst. In particular, L-prolinethioamide 1d (5 mol%), derived from L-proline and (R)-1-amino-indane, is shown as the most efficient organocatalyst studied promoting the direct aldol reaction of cyclo-alkyl, alkyl, and a-functionalized ketones with aromatic aldehydes in the presence of water and under solvent-free reaction conditions employing only 2 equivalents of nucleophile. Generally, anft-aldol products are obtained in high yields and excellent diastereo- and enantioselectivities (up to > 98/2 until syn, up to 98% ee). Solvent-free conditions give slightly higher dr and ee than using water as solvent. In addition, organocatalyst Id can be easily recovered by extractive work-up and reused. Prolinethio-amide Id (5 mol%) in combination with 4-NO2C6H4CO2H (5 mol%) is also a very effective or-ganocatalytic system for the asymmetric solvent-free intramolecular Haj os-Parrish-Eder-Sauer-Wiechert reaction with comparable or higher levels of enantioselectivity (up to 88% ee) to other reported catalysts in organic solvents.
