Rh-Catalyzed asymmetric hydroaminomethylation of α-Substituted acrylamides: Application in the synthesis of RWAY

The successful rhodium-catalyzed asymmetric hydroformylation and hydroaminomethylation of α-substituted acrylamides is described using 1,3-phosphite-phosphoramidite ligands based on a sugar backbone. A broad scope of chiral aldehydes and amines were afforded in high yields and excellent enantioselectivities (up to 99%). Furthermore, the synthetic potential of this method is demonstrated by the single-step synthesis of the brain imaging molecule RWAY.

Sugar based γ-amino alcohol organocatalyst for asymmetric Michael addition of β-keto esters with nitroolefins

Sugar based γ-amino alcohol was used in asymmetric Michael addition of β-keto esters with nitroolefins for the first time affording the corresponding several chiral Michael adducts bearing quaternary chiral carbon center in moderate to good chemical yields and stereoselectivities (up to 98%, up to dr. 95:5, up to 84% ee).

NOVEL DERIVATIVES OF ACYL CYANOPYRROLIDINES

A compound of formula (I) or a tautomeric form, regioisomer, stereoisomer, solvate, N-oxide or pharmaceutically acceptable salts thereof; wherein 'a' - is selected from the group consisting of substituted or unsubstituted heterocycloalkyl ring and substituted or unsubstituted carbohydrate moiety y is a member selected from -O-, -CO-, -S02-, aminoalkyl or formula (II) wherein, Rw is hydrogen, substituted or unsubstituted alkyl, alkenyl, alkynyl, cycloalkyl, aryl, heteroaryl; x is a member selected from -0-, -S-, -SO-, -S02-, CONR10, NR10CO and -NRd-, or x and y together represent a chemical bond; Z is selected from -CH-, -N-. t is an integer selected from O to 4; with the provisos that when 'a' is substituted or unsubstituted heterocycloalkyl ring then 't' is not O and when y = -CO-, x is not NRd.

Novel chiral xylofuranose-based phosphinooxathiane and phosphinooxazinane ligands for palladium-catalyzed asymmetric allylations

Novel chiral xylofuranose-based phosphinooxathiane and phosphinooxazinane ligands were found to provide high levels of enantioselectivity (up to 94% ee) in palladium-catalyzed asymmetric allylic alkylations and aminations.

Novel chiral xylofuranose-based phosphinooxathiane and phosphinooxazinane ligands for palladium-catalyzed asymmetric tandem allylic allylation

Novel chiral xylofuranose-based phosphinooxathiane and phosphinooxazinane ligands have been synthesized and found to be effective ligands for palladium-catalyzed asymmetric tandem allylic allylations of 1,4-diacetoxy-cis-2-butene with 2-(benzylamino)ethanol or 1,2-bis[benzylamino]ethane to give chiral 4-benzyl-2-vinylmorpholine (94% ee) or 1,4-dibenzyl-2-vinylpiperazine (70% ee).

Catalytic enantioselective reactions. Part 9. 1,2-O-isopropylidene-5-deoxy-5-N,N-dialkyl (or -N-monoalkyl)amino-α-D-xylofuranose derivatives as highly effective chiral catalysts for enantioselective addition of diethylzinc to aliphatic and aromatic aldehydes

A series of new 1,2-O-isopropylidene-5-deoxy-5-N,N-dialkyl (or -N-monoalkyl)amino-α-D-xylofuranose derivatives have been prepared from α-D-xylose and their enantioselectivities as chiral catalysts for the addition of diethylzinc to aldehydes have been examined. Of the chiral catalysts examined, 5-deoxy-1,2-O-isopropylidene-5-morpholino-α-D-xylofuranose provides high enantioselectivity for aromatic and relatively hindered aliphatic aldehydes, and 5-deoxy-5-hexahydroazepinyl-1,2-O-isopropylidene-α-D-xylofuranose is highly effective for unhindered aliphatic aldehydes.

Preparation of Novel Cyclophosphamide Derivatives of Sugars

Novel cyclophosphamide derivatives bearing a sugar structure were prepared by the treatment of the amino sugars from D-glucose and D-xylose with bis-(2-chloroethyl)aminophosphoric dichloride as well as with phosphoryl chloride and nucleophiles.
