摘要:The present invention relates to water soluble chiral sulfonated 2,2'-bis(diphenylphosphino)-1,1'-binaphthyl and its use as organometallic catalysts for asymmetric synthesis of optically active compounds. Asymmetric reactions of the present invention include those reactions in which organometallic catalysts are commonly used. Such reactions include, but are not limited to, reduction and isomerization reactions on unsaturated substrates and carbon--carbon bond forming reactions. Examples of such reactions include, but are not limited to, hydrogenation, hydroboration, hydrosilylation, hydride reduction, hydroformylation, alkylation, allylic alkylation, arylation, alkenylation, epoxidation, hydrocyanation, disilylation, cyclization and isomerization reactions. n The catalysts of the present invention provide the advantage of functioning in the presence of water without loss in enantioselectivity relative to the nonsulfonated BINAP catalyst in an organic solvent. As a result, the catalysts of the present invention may be employed in water, water miscible solvents, in aqueous--organic two phase solvent systems and in supported aqueous phase catalysts in organic solvents without loss in enantioselectivity. Further, the catalysts of the present invention may also be effectively employed in highly polar solvents such as primary alcohols and ethylene glycol. n The present invention also relates to a method for conducting asymmetric reactions on prochiral unsaturated bonds contained within a compound using the water soluble chiral sulfonated 2,2'-bis(diphenylphosphino)-1,1'-binaphthyl organometallic catalysts of the present invention.

标题 :Synthesis of a triangulene ring system and derivatives thereof

摘要:A three step synthesis of the 8,12-dihydro-4H-dibenzo[cd,mn]pyren-3a 2 -ylium cation (triangulenium cation) is effected by cascade cyclization of a tetra-benzyl alcohol precursor in triflic acid solution. This cation is easily observed by NMR and optical spectroscopy. Quenching of the cation into basic solutions or by hydride transfer from triethylsilane provides access to stable dihydro and tetrahydro[3]triangulenes. This route makes several [3]triangulene precursors more readily available for development of new applications in the field of molecular electronics.

标 题 :Synthesis of amides and amines from aldehydes or ketones by heterogeneous metal catalysis

权利人:ORGANOFUEL SWEDEN AB
摘要:A mild and efficient synthesis of primary amines and amides from aldehydes or ketones using a heterogeneous metal catalyst and amine donor is disclosed. The initial heterogeneous metal-catalyzed reaction between the carbonyl and the amine donor components is followed by the addition of a suitable acylating agent component in one-pot, thus providing a catalytic one-pot three-component synthesis of amides. Integration of enzyme catalysis allows for eco-friendly one-pot co-catalytic synthesis of amides from aldehyde and ketone substrates, respectively. The process can be applied to asymmetric synthesis or to the co-catalytic one-pot three-component synthesis of capsaicin and its analogues from vanillin or vanillyl alcohol. A co-catalytic reductive amination/dynamic kinetic resolution (dkr) relay sequence for the asymmetric synthesis of optically active amides from ketones is disclosed. Implementation of a catalytic reductive amination/kinetic resolution (kr) relay sequence produces the corresponding optically active amide product and optical active primary amine product with the opposite stereochemistry from the starting ketones.
