Synthetic investigations to achieve the six-membered core skeleton of Tamiflu using cis-aziridine as a chiral synthon has been presented. Present approach successfully utilizes intramolecular Horner-Wadsworth-Emmons reaction as the key step for the synthesis, whereas diene containing allylic aziridine framework is found to be inefficient to furnish six-membered core skeleton of Tamiflu through ring-closing
