The retro-ene reaction of 2-vinylcyclohexanols and approaches to the synthesis of botryococcene

Creator:: Rusay, Ronald Joseph
Abstract:: The retro-ene reaction of 2-vinylcyclohexanols occurs readily in the vapor phase at 400-450° producing unsaturated carbonyl compounds in good yields. The starting- materials were prepared in general by the carbenoid addition reaction of ethyl diazoacetate, appropriately substituted cyclohexene, and copper catalyst to produce bicyclic esters which were reduced to the...

The synthesis and spectral properties of 2,4-dioxabicyclo [3.3.1] nonanes

Creator:: Provant, Stephen Glenn
Abstract:: 3-Methyl-2,4-dioxabicyclo [3.3.1] nonane and 7-hydroxy-3-methyl-2, 4-dioxabicyclo [3.3.1] nonane were synthesized by the method of Croxall, Glavis and Neher, although in low yields. The structure of both compounds was proven by analytical methods and analysis of their spectral properties. Tentative configuration of C-3 in both compounds was assigned on the assumption...

Identification of a product of the Friedel-Crafts cyclization of β -(3- cyclohexenyl) propionyl chloride

Creator:: McEwen, Terry Earl
Abstract:: An improved procedure for the preparation of β-(3-cyclohexenyl) propionic acid from 4-vinylcyclohexene was developed. The Friedel-Crafts cyclization of β-(3-(3-cyclohexenyl) propionyl chloride with aluminum chloride was shown to give one bicyclic chlorine containing ketone in 41% yield. This ketone was identified by a combination of spectral and chemical methods as a...
