5-Methoxymethyl-2-furaldehyde: A Natural Furanoid from Jaborosa Magellanica (Solanaceae) 5-Methoxymethyl-furfural: ein natürliches Furanoid aus Jaborosa magellanica (Colanaceae)

It is known that when fructose or a carbohydrate which yields fructose, such as saccharose or inulin, is heated with methanol in the presence of dilute hydrochloric acid, dehydrative cyclization occurs with formation of 5-methoxymethyl-2-furaldehyde (1)1–3). In 1958, it was reported that furan 1 was present as a component of the roots of Asparagus lucidus, but it was assumed that this product had been formed as an artifact from fructose during the isolation process. Similarly, in 1978, it was stated that 5-methoxymethyl-2-furaldehyde was present in the extracts from flue-cured tobacco, apparently formed as an artifact from the reaction of fructose with sulfuric acid in methanol. 5-Methoxymethyl-2-furfural: ein naturliches Furanoid aus Jaborosa magellanica (Colanaceae)
