Abstract
Abstract Isomaltol ( 1 ), an enolic nonenzymic browning-product, decomposes in dilute acid to form the new red-orange colored, symmetrical dimer, ( E )-2-[1-(3-hydroxy-2-furanyl)ethylidene]-(2 H )-furan-3-one ( 2 ). Compound 2 was obtained in 20.4% yield with toluenesulfonic acid (⩾3 m ) at 50°. The structure for 2 was assigned on the basis of spectral data (m.s., u.v., i.r., 13 C- and 1 H-n.m.r.) and conversion into its mono- O -acetyl derivative ( 3 ).
