## Abstract Enantiopure (__R__)‐(+)‐[VCD(–)984]‐4‐ethyl‐4‐methyloctane (**1**), a cryptochiral hydrocarbon with a quaternary chiral center, was synthesized by the use of 2‐methoxy‐2‐(1‐naphthyl)propionate (MαNP) and (–)‐camphorsultam dichlorophthalic (CSDP) acid methods. The diastereomeric MαNP and
