Unusual Aromatization of 9-methyl-6-oxo-5-tosyl-6a, 7, 8, 10a-tetrahydroinden[2,3-b]indole
摘要:
9-Methyl-6-oxo-5-tosyl-6a,7,8,10a-tetrahydroindeno[2,3,b]indole (Ⅱ) was aromatized by PPE, CF3COOH or BF3·Et2O to furnish the new compound, 9-methyl-5-tosyl-6H-indeno[2,3,b]indole (Ⅷ), involving an unusual"dehydration";the loss of two H's and concomitant exocyclic (to the aromatized carbocycle) removal of the carbonylic oxygen.
