RING PUCKER IN DIHYDROAROMATIC EPOXIDES - THE MOLECULAR-STRUCTURE OF METHYL-T,T-3,4-EPOXY-1,2,3,4-TETRAHYDRONAPHTHALENE

The crystal structure of the derivative of tetrahydronaphthalene with substituent epoxy, hydroxyl, and methyl groups in the more saturated r ing ethyl-t,t-3,4-epoxy-1,2,3,4-tetrahydronaphthalene) has been determ ined. The hydroxyl and methyl groups are both found to be equatorial. The crystal structure is characterized by chains of molecules linked b y O-H...O hydrogen bonds involving the hydroxyl groups; these hydrogen bonds lie approximately parallel to the b axis. The conformations of the epoxide-bearing rings in various hydroxy epoxides are compared and shown to be similar.
