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.

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.
