A simple and stereoselectivesynthesis of 3‐methylthalidomide, a configurationally stable thalidomide analog, is presented. Herein we describe the synthesis of (R)‐3‐methylthalidomide starting from (S)‐alanine by piperidin‐2‐one ringassemblyapproach in high yield and enantiomeric purity without using a chiral auxiliary or reagent. Starting from (R)‐alanine, the corresponding (S)‐3‐methylthalidomide
