active alcohols are the potential chiral building blocks for the synthesis of pharmaceutically important molecules and asymmetricchiral ligands. Hence, this biocatalytic approach is found to be the most suitable for the preparation of a wide range of chiralalcohols and gave inspiration for the development of a new biotechnological process.

The present invention relates to an enzymatic process for the preparation of optically active chiral alcohols using tuberous root Daucus carota; particularly invention relates to an enzymatic process for the preparation of optically active alcohols by enantioselective reduction of corresponding ketones using tuberous root Daucus carota.
Iodobenzene‐catalyzed synthesis of α‐azidoketones and α‐thiocyanatoketones fromarylketones with MCPBA as a cooxidant is described. The method is simple, rapid and practical, generating α‐azidoketones and α‐thiocyanatoketones from the arylketone without isolation of α‐tosyloxyketones in good to excellent yields.
The reaction of aryl ketones with sodium azide using polymer-supported bis(trifluoroacetoxyiodo)-benzene (PSBTI) in the presence of trifluoroacetic acid (TFA) to prepare α-azidoketones in one-pot conditions is reported.
