    • Iodocyclization of the corresponding E-isomer under the established conditions proceeded with poor enatioselectivity and moderate chemical conversion (11% ee and 50% yield).

    • To investigate the possible involvement of HCl in the cyclization, which might be generated in situ, iodocyclization of 6 was carried out using 0.15 equiv of NCS and 0.6 equiv of HCl instead of 0.75 equiv of NCS to provide (R)-7 in 81% ee and 39% yield.

    • Iodocyclization of 6 was scaled up to 2.6 mmol with comparable enantioselectivity and chemical yield (85% ee and 89% yield).
