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...

Ring expansion reactions of alkoxides and their application toward synthesis of large ring hormone models

Creator:

Seitz, Earl Philip

Abstract:

The potassium salts of a series of 1-vinylcycloalk-3-en-l-ols were found to undergo ring expanding [1, 3]-sigmatropic shifts at 25° when dissolved in hexamethylphosphoramide (HMPA) or 1, 2-dimethoxyethane (DME) with 18-crown-6. The yields and reaction rates were compared with those of the corresponding Siloxy-Cope ring expansions. These anionic cases showed about...
