5-TETRACYCLO2,4.03,6>OCT-7-ENYL CARBENE; AN ATTEMPTED SYNTHESIS OF A FENESTRANE DERIVATE.

The title carbene was generated at low temperature with the objectiv to effect intramolecular cyclopropanation of its double bond.Labelling studies showed intramolecular C-C bond insertation followed by intramolecular reverse Diels Alder reaction to be the major pathway to the products.

Chemistry of 2-Carbenabicyclonona-3,6,8-triene

Pyrolysis of the lithium salt of the tosylhydrazone of bicyclonona-3,6,9-trien-2-one (10) produces indene and 7-ethynyl-1,3,5-cycloheptatriene.As an aid in analyzing likely carbene to carbene rearrangements, the pyrolytic decomposition of the lithium salt of tricyclo4,9>nona-2,6-dien-5-one tosylhydrazone was studied and found to result in the formation of indene as the sole volatile product.The decomposition of the lithium salt of tosylhydrazone 10 is discussed in terms of carbenes 13, 15, 16, and 6a and allene 14.
