Dehydration of 2-hydroxy-8-R-tricyclo[7.3.1.02,7]tridecan-13-ones (R = H, Me, Ph) effected by various reagents provided 8-R-tricyclo[7.3.1.02,7]tridecen-13-ones with different positions of the double bond. In the presence of phosphoric acid arise isomers with the double bond in 2(3) position, a mixture of hydrochloric and acetic acid primarily affords isomers with the double bond in 2(7) position that further migrates into 7(8) position at R = Me, Ph.

Substituted 4H-pyrans were obtained in high preparative yields by the reaction of 1,5-diketones with acetic anhydride and boron trifluoride etherate in diethyl ether.It is assumed that the heterocyclization of 1,5-diketones includes a step involving the f
