We recently reported a new C3-symmetric (R)-phenylglycinol N-1,3,5-benzenetricarboxylic acid-derived chiral high-performance liquid chromatography (HPLC) stationary phase (CSP 1) that demonstrated better results as compared to a previously described N-3,5-dintrobenzoyl (DNB) (R)-phenylglycinol-derived CSP. Over a decade ago, (S)-leucinol, (R)-phenylglycine, and (S)-leucine derivatives were used as the starting materials of 3,5-DNB-based Pirkle-type CSPs for chiral separation. In this study, three new C3-symmetric CSPs (CSP 2, 3, and 4) were prepared by combining the ideas and results mentioned above. Here we describe the synthetic procedures and applications of the new C3-symmetric CSPs (CSP 2?CSP 4).

A concise and general route to secolignans has been developed. The first total synthesis of secolignans peperomin A (1a), peperomin C (1b), and peperomin D (1c) was accomplished in ?28% overall yield over five synthetic steps. Peperomin analogs (1d) and (1e), possessing two differentially substituted aryl groups, were synthesized by a highly selective conjugate addition. The overall yield for the analogs 1d and 1e were 27 and 26%, respectively.

This work describes the first examples of diastereoselective intramolecular cyclopropanations of a de novo class of push-pull carbenes derived from DMDO-epoxidations of chiral ynamides. This reaction sequence essentially constitutes a tandem epoxidation-cyclopropanation that effectively gives rise to a series of structurally unique amido-cyclopropanes. A plausible mechanistic model is proposed revealing insights into this novel cyclopropanation process.

An asymmetric aldol strategy has been developed for the synthesis of L- daunosamine and D-ristosamine derivatives starting from noncarbohydrate precursors. Lithium and boron enolate mediated aldol reactions of 12 with O- TBS lactaldehyde gave non-Evans syn and Evans syn aldol products, respectively, with high selectivity. The chemical efficiency of the lithium enolate reactions were higher than the corresponding reactions with the boron enolates. Curtius rearrangement of lactone acids 23 and 26 gave the corresponding N-BOC amino lactones 30 and 32 in 64% and 62%, respectively, with complete retention of configuration. Lactone 30 was converted by a two- step sequence to N-benzoyldaunosamide 40. The overall yield for the amino sugar 40 was 18% over six steps. Similary, lactone 32 was converted to N- benzoylristosamide 42 with an overall yield of 18% starting from 12.

A highly regio- and stereoselective synthesis of I±-fluorinated imides via fluorination of chiral enamides

A highly I¿-facial selective and regioselective fluorination of chiral enamides is described. The reaction involves an enantioselective fluorination exclusively at the electron-rich enamide olefin with N-F reagents such as Selectfluor and N-fluoro-benzenesulfonimide [NFSI] accompanied by trapping of the I²-fluoro-iminium cationic intermediate with water. The resulting N,O-hemiacetal could be oxidized using Dess-Martin periodinane, leading to an asymmetric sequence for syntheses of chiral I±-fluoro-imides and optically enriched I±-fluoro-ketones.

Absolute configuration of lactams and oxazolidinones using kinetic resolution catalysts

A simple method for determining the absolute configuration of oxazolidinones, lactams, and their derivatives using kinetic resolution catalysts is described. The optically pure substrates were acylated using the (S)-HBTM and the (R)-HBTM catalyst, and the faster reaction was determined.

A new methodology for the synthesis of beta-amino acids

A differentially functionalized succinic acid unit 6 undergoes alkylation with excellent regio- and high stereocontrol at the carbon alpha to the imide to furnish the alkylated product 7 in 60-83% yield. Selective removal of the imide provides 8 in 80-90% yields. Curtius rearrangement of 8 with retention of stereochemistry provides N-protected beta-amino acids (9) in 70-83% yields. Alternatively, selective deprotection of the ester group followed by Curtius rearrangement provides isomeric beta-amino acids 14a, 14b, and 14e in good yields. The methodology has been successfully applied to the synthesis of N-Boc-iturinic acid and 2-methyl-3-aminopropanoic acid, components of the antifungal peptide iturin and the cytotoxic depsipeptide cryptophycin respectively.
