A novel and versatile approach has led to the synthesis of various classes of mono- and bidentate phospholane and phosphinite ligands based on a benzothiophene scaffold. The ligand functions in the bidentate ligands can be introduced independently and consecutively. A bis-phospolane ligand as well as its rhodium complex have been characterized by crystal-structure determinations. The bis-phospholane ligands were tested in the catalysed asymmetric homogeneous hydrogenation of dehydroamino acid derivatives, enamides and itaconates and gave ee values of up to 98.7 %.

Some new organometallics of ruthenium(II) of the type [RuCl2(COD)(CO)L] (1a-f) and [RuCl2(COD)L2] (2a-f) (where L is substituted tertiary phosphines), have been synthesized by using precursors [RuCl2(COD)(CO)(CH3CN)] (1) and [RuCl2(COD)(CH3CN)2] (2) with the substituted tertiary phosphine ligands in 1:1 and 1:2 molar ratio. The organometallics (2a-f) have been further reacted with carbonmonoxide to produce compounds of the type [RuCl2(CO)L2] (3a-f). These compounds were characterized by elemental analysis, IR, NMR (1H, 13C and 31P), mass and electronic spectral data. The catalytic activity of all these organometallics were studied and found that they are efficient catalysts for hydrolysis of etofibrate. The hydrolyzed product was separated by column chromatography and the percent yields are found in the range of 98.6-99.1%.

(1S,2S)-3-Trifloxy-cis-1,2-dihydrocatechol acetonide, a useful chiral building block, was prepared from d-ribose in good overall yield using a carbonyl allylation and a ring-closing metathesis as the key C-C bond-forming steps. Negishi cross-coupling of this triflate with a serine-derived organozinc iodide proceeded efficiently to afford an alpha-amino acid derivative as a potential precursor for scabrosin esters (ambewelamides).

An efficient synthesis of N-fused polycyclic indoles by a palladium-catalyzed annulation/acyl migration cascade reaction is described. The reaction is ligand-free, scalable, and provides access to a diverse range of useful indole scaffolds from readily available starting materials. Supporting mechanistic studies indicate that the reaction likely proceeds via an intramolecular alpha-arylation mechanism. The synthetic utility of this protocol is demonstrated by a gram-scale reaction and syntheses toward indole alkaloids and a HSP90 inhibitor.

Our results show that the stereoselectivity of the Wittig-reaction can be controlled by the variation of substituents in accord with the ORDERING CONCEPT OF ALTERNATIV PRINCIPLES (individual pairs, known and unknown classes of alternatives).The “all-phenyl Wittig-system” having three phenyl groups on phosphorous two in ylid- and aldehyd-position was chosen as a standard for our investigations.Differentiation in ylid-position and compensation on phosphorous and aldehyd-position were observed by the comparison of “patterns”.Consequently, most of the selectivity rules of Wittig-reactions can be explained by the differentiation through alternatives in the ylid-position.Inversion or conservation of the “patterns” of measured data points to the variation in structure of starting materials, reaction rates and selectivities.Amount-controls were also described in certain systems.

We describe here the synthesis and structural characterization of two new classes of ambiphilic, N-boryl imine ligands, wherein boron is associated with a Lewis basic imine nitrogen. These ligands can be easily generated in two steps from the corresponding pyridinyl- and phosphinyl-tethered aldehydes. 11B NMR analysis suggests the association of the Lewis acidic boron to either the pyridine unit or via intermolecular acid/base interactions with the imine. Both of these ligands can coordinate to palladium, and their structures were confirmed by X-ray crystallography..
