Reactions with Oxalate Synthesis of 2,6-Dioxabicyclo-Octa-3,7- Dienes or o-Benzoquinones

2 Reactions with Oxalate Synthesis of 2,6-Dioxabicyclo [3.3.0]-Octa-3,7- Dienes or o-Benzoquinones 

Addition of organolithium reagents to isothiocyanates has been a fundamental protocol for the preparation of a wide variety of S-, N-, and 0-containing linear and cyclic compounds. Isothiocyanates reacted with 1,4-dilithio-l,3-butadienes 1 to afford iminocyclopentadiene or indenimine derivatives in excellent isolated yields
