✦ Synopsis

The degradation of fructose with aqueous Ca(OH) 2 gives products similar to the same reaction with glucose. The fructofuranosyl linkage in glycosides cleaves at 130-140°C and the fructose so released degrades to products that are different in proportion to those from free fructose under similar reaction conditions. Non-reducing glycopyranosides are resistant to alkaline degradation at lower temperatures, methyl ot-o-glucopyranoside and or, ot'-trehalose at even 250°C. For purposes of comparison, the alkaline degradation of glucose, lactose, and xylose was also studied. The relative contributions of the intermediate enediols to the reaction pathways are discussed.

Cephradine yields an unique alkaline degradation product, which has been identified by proton magnetic resonance, IT-NMR, and mass spectrometry as 2-[6-(1,4-cyclohexadine-lyl) -2.5dioxo -3piperazinyl] -5,6-dihydro -5methyl -2H-1,3thiazine-4carboxylic acid, sodium salt.

## Abstract A kinetic study on the alkaline hydrolysis of cephaloridine (1) at pH 10.5 and 37° was carried out using ion‐pair reversed‐phase HPLC. The main resulting degradation products, the 7‐epimer 2 of 1, the Δ^2^‐isomer 3 of 1, and the 3‐methylidene compound 4 were identified. The presence of
