    摘要: A new compound, 2-(1'' -hydroxymethyl - ethyl) -5- methyl-5-vinyl - tetrahydrofuran has been discovered in an essential oil of a lilac flower. This compound consists of four steroisomers and is useful as an ingredient to be incorporated in floral perfumes. This compound is obtained by selectively reducing the formyl radical of 2- (1'' formylethyl) -5- methyl-5- vinyl tetrahydrofuran.
