Leaf alcohol Usage And Synthesis


Description

Leaf alcohol exists as a liquid at room temperature with a characteristic odor of green leaves. It is found in green tea, violet leaf oil, and many types of leaves, herbs, and grasses. Leaf alcohol finds applications in perfumery as floral fragrance. Leaf alcohol is also investigated for its antidiabetic activity.

Chemical Properties

colourless liquid

Chemical Properties

Leaf Alcohol is a colorless liquid with the characteristic odor of freshly cut grass. In small quantities, leaf alcohol occurs in the green parts of nearly all plants. The volatile flavor constituents of green tea contain up to 30%.
A stereospecific synthesis of (Z)-3-hexen-1-ol starts with the ethylation of sodium acetylide to 1-butyne, which is reacted with ethylene oxide to give 3-hexyn-1-ol. Selective hydrogenation of the triple bond in the presence of palladium catalysts yields (Z)-3-hexen-1-ol. Biotechnological processes have been developed for its synthesis as a natural flavor compound, for example.
Leaf alcohol is used to obtain natural green top notes in perfumes and flavors. In addition, it is the starting material for the synthesis of (2E,6Z)-2,6-nonadien-l-ol and (2E,6Z)-2,6-nonadien-l-al.

Chemical Properties

cis-3-Hexen-l-ol has an intense, green odor, not as strong as the corresponding aldehyde and a characteristic herbaceous, leafy odor on dilution. This substance can be obtained through extraction from various essential oils and purified by reacting it to the corresponding phthalate or allophanate; it was synthesized by Ruzicka and Schinz, who also clarified its chemical structure; Stoll and Rouve reported on the most significant differences between the natural and the synthetic products.
