A new class of chiral bicyclic [1,2,3]-triazolooxazine derived N-heterocyclic carbene (NHC) ligands was synthesised in its enantiopure form from commercially available, cheap amino acid without undertaking any chiral resolution. In particular, the bicyclic N-heterocyclic carbene precursor, (S)-7-benzyl-6,6-(R1)2–2-R2-[1,2,3]-triazolooxazinium iodide [R1 = R2 = Me (1a); R1 = H, R2 = Me (2a); R1 = H, R2 = Et (3a)] salts were conveniently prepared by the N-alkylation reactions of the corresponding [1,2,3]- triazolooxazine derivatives with alkyl iodides in ca. 37–73% yields. The copper mediated [3 + 2] cycloaddition reaction of the PhCH2CH(N3)CR2OH (R = H, Me) azido alcohol compounds and propargyl bromide gave the desired [1,2,3]-triazolooxazines. These chiral bicyclic [1,2,3]- triazolooxazine derived N-heterocyclic carbene ligands were characterised in the form of its silver (NHC)AgCl (1–3)b, gold (NHC)AuCl (1–3)c, and the palladium (NHC)2PdCl2 (1–3)d and the PEPPSI type (NHC)PdI2(NC5H5) (1–3)e complexes (NHC = (S)-7-benzyl-6,6-(R1)2–2-R2-[1,2,3]-triazolooxazin-3-ylidene; R1 = H, Me and R2 = Me, Et; PEPPSI = Pyridine Enhanced Precatalyst Preparation Stabilisation and Initiation).
