天然物の起源Reported found in nature; the ethyl l-methylbutyrate has been identified in strawberry juice; because of the presence of the asymmetric carbon, the compound should exhibit optically active forms as well as the racemic form; however, only the d-form and the racemic form are known. Reported found in apple juice, orange and grapefruit juice, bilberry, pineapple, strawberry, cheeses, milk, cognac, rum, whiskey, cider, mango, mountain papaya, spineless monkey orange (Strychnos madagasc.), Chinese quince and German chamomile oil.

一般的な説明A colorless oily liquid with a fruity odor. Insoluble in water and less dense than water. Flash point 73°F. Contact may irritate skin, eyes and mucous membranes.

調製方法

製造方法The racemic form can be prepared catalytically by several methods: from butene and Ni(CO)4 under nitrogen in ethyl alcohol/acetic acid solution, or from ethylene and CO under pressure using HBF4 and HF as catalysts.
