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...

Preparation and reactions of 7-bicyclo [3.3.1] nonen-2-one

Creator:: Salisbury, Kirby Grant
Abstract:: 2-Carboxy-3(3-cyclohexen-1-yl)propionic acid, 3-(3-cyclohexen-1-yl)propionic acid and 3-(3-cyclohexen-1-yl)propionyl chloride were prepared in sequence from ethyl-2-carbethoxy-3-(3-cyclohexen-1-yl)propionate. Cyclization of 3-(3-cyclohexen-1-yl)propionic acid in polyphosphoric acid resulted in the formation of 4, 5, 6, 7-tetrahydroindanone which was identified by its ultraviolet spectrum and its physical properties. 7-Bicyclo[3.3.1] nonen-2-one was prepared by a Friedel-Crafts cyclization of 3-(3-cyclohexen-1-yl)-propionyl...

Exploratory studies of the mechanism of 1,3 sigmatropic ring expansion reactions

Creator:: James, Corinne Patricia
Abstract:: The potassium salts of certain 1-vinylcycloalk-3-en-l-ols have been found to undergo sigmatropic ring expansion rearrangements in HMPA. Preliminary investigations of several benzo-substituted medium ring systems were undertaken in order to determine which of these was best suited for further study. A synthetic sequence leading to the formation of 5-methy1-6-viny1-7,8,9,10-tetrahydro-6-benzocyclo-octenol, which...
