ELECTROREDUCTIVE CYCLIZATION. A COMPARISON OF THE ELECTROCHEMICAL AND ANALOGOUS CHEMICAL (MIRC) REACTION
Nugent, Sean T.,Baizer, Manuel M.,Little, R. Daniel
, p. 1339 - 1342 (1982)
Several examples which illustrate the contrasting and complementary aspects of electroreductive cyclization and MIRC reactions are presented.A brief mechanistic discussion of the electrochemical reaction is given and two examples of the use of an electroc
Tetramethyl 1,1,4,4-Cyclohexanetetracarboxylate: Preparation and Conversion to Key Precursors of Fluorinated, Stereochemically Defined Cyclohexanes

Stereoselective low-temperature diisobutylaluminum hydride (DIBALH) reduction of the litle tetraester 3 affords trans-1,4-dialdehyde 4a as the major product.Fluorination of 4a,b, followed by additional elaboration leads to novel, 1,1,4,4-tetrasubstituted cyclohexanes bearing trans-1,4-difluoromethyl and fluoromethyl groups.The effect of ring size and number of ester substituents on the outcome of the reduction has been examined and treatment of dimethyl 1,1-cycloalkyl diesters 7a-c with excess DIBALH results in reduction of only one ester group.An entry into trans-1,4-trifluoromethylated tetrasubstituted cyclohexanes has been gained through stereoselective SF4 fluorination of 1,1,4,4-cyclohexanetetracarboxylic acid 17.Stereochemical assignments are supported by X-ray crystallographic data.
