Organolithiumreagents (RLi; where R = ethyl, isopropyl,cyclopropyl,n-butyl, sec-butyl, t-butyl, vinyl) have been found to add regiospecifically to (—)-nicotine to provide a series of 6-substituted nicotinoids of low optical activity. The data presented for the organolithiumadditions coupled with an analysis of the addition oft-BuLi to(—)-nicotine and [2'-2H]nicotine have provided strong evidence
