Oxidative allylation to sp(2)- and sp(3)-carbon attached to the nitrogen atom was accomplished. The alpha-allylation of tertiary amines was catalyzed by easily available hydrated iron(III) chloride in combination with air or aqueous (t)BuOOH. Remarkably, N-allyl- and N-propagyl-tethered tertiary amines were also allylated through this protocol.

A novel and practical procedure for the synthesis of small molecules possessing beta-hydroxy or N-tosylamino 1,2,3-triazole motif by azidation of epoxides or N-tosylaziridines with sodium azide followed by "click reaction" using eco-friendly PEG-400 as a reaction medium in the presence of 5 mol % of CuI is described. Enantiomerically pure epoxide and N-tosylaziridines were afforded in high yield with excellent ee values maintaining complete stereospecificity.

The ‐O‐Tf substituent can be replaced by treatment with organometal reagents where the use of zinc bromides is found to be the most efficient one.

The syntheses of enantiomer-enriched orthogonally protected different (2S)-2,3-diaminopropanoates and unnatural furyl-substituted (tert-butoxy)carbonyl (Boc) as well as (benzyloxy)carbonyl (Cbz) protected amino acid esters are accomplished by means of an enantioselective aza-Henry reaction. A key feature of this protocol is organocatalysis as a genesis of chirality to ensure high enantioselectivity.
