The full report on the synthesis of the hexano-bridged oxepin (140) has now appeared and further work has been reported on its oxidative cleavage to give cyclodecenes and cyclodecadienes, and on some addition reactions. The structure of the dehydration product of 2,6-di-t-butyl-4-phenyl-l-(p-tolyl)cyclohexa-2,5-diene-l,4-diol, previously postulated as a fully unsaturated oxepin, has now been confirmed by X-ray analysis. ... 

The reaction of two lysyl residues with two molecules of glucose creates the so-called crossline (cross-linked AGE) (4-233), which is found in the serum and kidneys of diabetic patients. An analogous structure, called fluorolink (4-234), actually arises by dehydration and oxidation of crossline. Another cross-linked AGE is imidazolium salt of glyoxal-lysine dimer, trivially called GOLD (4-235), which is 2-ammonio-6-(l-(5-ammonio-6-oxido-6-oxohexyl) imidazolium-3-yl]hexanoate. The compound known as MOLD, (2-ammonio-6-[l-(5-ammonio-6-oxido-6-oxohexyl)-4-methyHmidazolium-3-yl] hexanoate (4-236), results from the analogous reaction with methylglyoxal. These examples, however.
