Facile, alternative syntheticroutes to 6, (R)‐6, and (S)‐6‐3‐benzyl‐N‐(2,6‐dimethylphenyl)‐1,3‐oxazolidine‐4‐carboxamides (6), a chiral oxazolidine derivative of tocainide, are reported. The syntheticroutes described herein also afforded 11‐, (R)‐11‐, and 12, which present the imidazolidin‐4‐one core and belong to a class of compounds interesting for their biological activities. All the final compounds
