✦ Synopsis

In an extension of our studies on the thermal decomposition of Amadori compounds (l), we have identified 2,3-dihydro-3,5-dihydroxy-6-methyl-4&pyran-4-one (Ia) as the major solid product that is volatilized during the pyrolysis of l-deoxy-l-(k-prolino)-&fructose at 138"/1 mm. The structural assignment is significant because it identifies an abundant volatile product formed from a Maillard reaction intermediate, which is highly important in the

## Abstract The thermal decomposition of the title compound has been studied in the gas phase in the temperature range of 584–634 K. The decomposition was found to be a first‐order homogeneous process yielding 2‐methylbuta‐1,3‐diene and formaldehyde. The rate constants obtained at 11 temperatures w
