In a previous paper') we described the generation of o-lithiomethylphenyl isocyanide, which was a versatile reagent for syntheses of indole derivatives. Herein, we wish to report an elaboration of the lithiomethylphenyl isocyanide to lead to heterocycles such as 4,5-dihydro-3,1-benzoxazepine ~~ and
