“…One convenient 5-methylfurfural synthesis by Scott and Johnson (1932) involves slow addition of fructose or sucrose to a boiling mixture of aqueous sulfuric acid and stannous chloride. Volatile products are steam-distilled from the mixture as they are formed and the odor of hydrogen sulfide is apparent.…”

The analysis of a coffee concentrate is described: 202 constituents have been identified, 154 of which for the first time. Some of these compounds are new chemicals; their synthesis is described. Most identifications are based upon mass spectrometry combined in many cases with IR. spectrometry and comparison with reference compounds. MS. and IR. data are given in detail. The analysis shows that a large number of minor constituents is present, many of which could not be identified.

The synthesis of furan derivatives by treatment of an α‐halo ketone and β‐dicarbonyl compound with a base is known as the Feist‐Bénary condensation. The bases used are normally ammonia and pyridine, however, it was found advantageous to use aqueous pyridine to effect this reaction instead of ammonia, because the production of pyrrole derivative is obviated and the yield of the furan derivative is increased. The intermediate dihydrofuran has been isolated with good diastereoselectivity under mild conditions. This reaction has been extended to prepare furan from α,β‐dichloroethyl ether and β‐ketoester in aqueous pyridine solution to reduce the formation of pyrrole.
