Abstract
Trimethylsilylketene smoothly reacts with 8-azaheptafulvenes to give 3, 3a- dihydro-3-trimethylsilyl-1-azaazulen-2(1H)-ones, the [8+2] cycloadducts, in excellent yields. Furthermore, trimethylsilylketene also undergoes the [62] cycloaddition reaction with 6-amino-1-azafulvenes to afford 1H-pyrrolizi n-3(2H)ones.
