Methyl-2-furoic acid has been prepared by the oxidation of 3-methyl-2-furaldehyde 4 and by the degradation of 3-methyl-2-isovalerylfuran (Elsholtzia ketone).5 3-Methylfuran has been prepared by the present method 6 and more recently by a three-step method starting with methallyl chloride and ethyl orthoformate.7 Circuitous routes from citric acid 8 and malic acid 9 have also been used. 

Perilla frutescens can be class ed in several chemotypes as well according to the main mono-terpene components perillaldehyde, elsholtzia ketone, or perilla ketones and on the other side phenylpropanoid types containing myristicin, dillapiole, or elemicin (Koezuka et al., 1986). A comprehensive presentation on the chemotypes and the inheritance of the mentioned compounds was given by this author in Hay and Waterman (1993). In the referred last two examples, not only the sensorial but also the toxicological properties of the essential oil compounds are decisive for the (further) commercial use of the respective species biodiversity.
