then of Ramberg-Backlund elimination to a substituted olefin. The alkylations are clean and regiospecific, often amenable to one-pot operation, and in most cases the elimination is smooth. A variety of examples is presented to establish the scope of the method, and the mechanism and stereochemistry are discussed. Nuclear Synthons. In our examination of the logic of synthesis design* we directed attention

The present invention relates to the isomerization of cis,cis and/or cis,trans muconic acid or esters thereof to trans,trans muconic acid or esters thereof and to the esterification of such muconic acids.
Exocyclic deprotonation and α alkylation with methyliodide of title compounds have been observed. A clarification of Hagemann ester ethylene ketal reactivity toward strong bases is given.
The present invention relates to cyclohexanes having carboxylate derivatives at the 1 and 4, and optionally the 2, position. The invention also relates to processes for preparing such compounds wherein a portion of the starting materials utililzed is derived from renewable resources.
