Abstract
The reaction of substituted spirocyclopropenes 1 with 1-(3,5-dinitrophenyl) -3,4-dihydroisoquinoline 2 in dry ether solution afforded not only the expe cted THI 4 by 1,5-electrocyclization but also novel fluorenespiroazanorcara dienes 5 which is the first intramolecularly trapped product of the key int ermediate in the formation of indolizine photochromics.
