Abstract: Both intermolecular reactivities toward C-O and C-N unsaturated substrates and intramolecular reactions of various 1-lithio-1,3-dienes are briefly summarized. Results reveal that intramolecular synergy between the alkenyllithium moiety and the butadienyl skeleton make 1-lithio-1,3-diene derivatives useful and unique as building blocks in organic synthesis. It is demonstrated that substitution patterns and the nature of the substituents on the butadienyl skeleton have remarkable effects on reaction pathways.
