A novel and efficient approach to highly substituted indolizines via 5-endo-trig iodocyclization
摘要:
A new approach to indolizines has been developed using a 5-endo-trig iodocyclization of allylic esters followed by isomerization and dehydroiodination facilitated by triethylamine at rt This mild procedure enabled us to synthesize a number of highly substituted indolizines in good yields.
