An easy and straightforward preparation of pyrrole-embedded aza-heterocyclic scaffolds employing a Ru/B-H binary catalyst system has been developed. The strategy generates a diverse array of privileged scaffolds from 2-aminophenyl group appended pyrroles that can be prepared by a two-step process from corresponding aminoaryl-substituted pyrroles. The technique of incorporating 2-aminoaromatic groups in the heterocycles and their subsequent ring-closing-metathesis (RCM) isomerization followed by subsequent Pictet-Spengler type reaction should also be applicable to other heterocycles for generating a library of multi-ring compounds in an efficient manner.

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 rhodium-catalyzed three-component reaction of diazo compounds, anilines and C,N-cyclic azomethine imines via trapping of transient ammonium ylides was developed. This reaction provided a simple and convenient approach for the synthesis of pharmaceutically intriguing tetrahydroisoquinoline derivatives in moderate to good yields (36-85%) with good diastereoselectivities (up to 95 : 5 dr) under mild reaction conditions.

Unprecedented asymmetric copper-catalyzed addition of ZnEt2 (ZnBu2) to the exocyclic C=C bond of pentafulvenes C5H4(=CHAr) (Ar=2-MeOPh and related species) results in enantiomerically enriched (up to 93:7 e.r.) cyclopentadienyl ligands (C5H4CHEtAr; abbreviated CpR). Copper catalyst promotion with both chiral phosphoramidite ligands and a phosphate additive is vital in realizing both acceptable enantioselectivities and reaction rates. Enantiomeric CpR2TiCl2 complexes have been prepared; the (S,S) isomer is twice as active towards pancreatic, breast, and colon cancer cell lines as its (R,R) enantiomer at 24 h.

A tandem phenol oxidation-Michael addition furnishing oxo- and -aza-heterocycles has been developed. Dirhodium caprolactamate [Rh 2(cap)4] catalyzed oxidation by T-HYDRO of phenols with alcohols, ketones, amides, carboxylic acids, and N-Boc protected amines tethered to their 4-position afforded 4-(tert-butylperoxy)cyclohexa-2,5-dienones that undergo Bronsted acid catalyzed intramolecular Michael addition in one-pot to produce oxo- and -aza-heterocycles in moderate to good yields. The scope of the developed methodology includes dipeptides Boc-Tyr-Gly-OEt and Boc-Tyr-Phe-Me and provides a pathway for understanding the possible transformations arising from oxidative stress of tyrosine residues. A novel method of selective cleavage of O-O bond in hindered internal peroxide using TiCl4 has been discovered in efforts directed to the construction of cleroindicin F, whose synthesis was completed in 50% yield over just 3 steps from tyrosol using the developed methodology.

The phosphate ester 1,1?-binaphthyl-2,2?-diyl-phosphate shows an intense fluorescence of the binaphthyl moiety. In the complex 1,1?-binaphthyI-2,2?-diyl-phosphato-pentaammine-cobalt(III) this emission is quenched by excited state electron transfer to Co(III). As a consequence the phosphate ester undergoes an oxidative cleavage while Co(III) is reduced to Co(II) with phi=0.023phi0.002 at lambdairr=313 nm. WILEY-VCH Verlag GmbH, 1998.

A series of 1,1?-binaphthalene-2,2?-diyl phosphate (BNPPA -) salts have been synthesized. Their crystal packings show a separation of the hydrophobic naphthyl and hydrophilic (RO)2PO 2- phosphate/cation/solvate regions. Hydrogen bonding in the latter is the driving force for “inverse bilayer” formation, with a hydrophilic interior exposing the hydrophobic binaphthyl groups to the exterior. Stacking of the inverse bilayers occurs less through pi-pi and more through CH…pi interactions between the naphthyl groups, which correlates with the formation of thin crystal plates along the stacking direction. Cations used with R- or rac-BNPPA- are protonated isonicotin-1-ium amide (1), isonicotin-1-ium acid (2), guanidinium (3), the metal complexes trans-tetraammine-dimethanol-copper(II) (4), trans-diaqua-tetramethanol-copper(II) (5) and cis-diaqua-bis(ethylene diamine)-nickel(II) (6). Crystallization occurs with inclusion of water and methanol solvent molecules, except in 2. Starting from R-BNPPA, inversion takes place with calcium acetate to give 1 as the racemate. 2 is crystallized as the R-BNPPA salt. The inversion-symmetrical complex trans-[Cu(H2O) 2(CH3OH)4]2+ in 5 has Cu-OH 2 bond lengths of 1.937(4) A, and Cu-O(methanol) of 2.112(4) and 2.167(4) A, corresponding to a compressed tetragonal geometry. the Royal Society of Chemistry the Centre National de la Recherche Scientifique 2006.
