Diazo Compounds as Electrophiles To React with 1,4-Dilithio-1,3-dienes: Efficient Synthesis of 1-Imino-pyrrole Derivatives
摘要:
1-Imino-pyrrole and indole derivatives were synthesized in high yields from the reaction of diaryl diazomethanes with 1,4-dilithio-1,3-dienes. Diaryl diazomethanes reacted as electrophiles in this reaction. An unprecedented Zn-complex was formed via transmetalation of the above reaction intermediate with ZnCl2 and was structurally characterized. The trans-mu(2)-eta(1):eta(1) coordination mode in the solid state for this azaallylzinc compound was observed.
