METHOD OF PREPARING (6R,10R)-6,10,14-TRIMETHYLPENTADECAN-2-ONE (PHYTON) Russian patent published in 2003 - IPC

Abstract RU 2197465 C2

FIELD: organic synthesis. SUBSTANCE: invention relates to synthesis of terpenoid ketones, in particular to improved method for preparation of phyton, which can be used in synthesis of vitamins E and K. Method consists in extracting leaves of nettle diclinous, urtrica dioica, followed by ozonolysis of obtained extract in aqueous acetone by way of passing through the latter ozone-oxygen mixture in presence of barium hydroxide. Precipitate is further filtered off, filtrate evaporated, and the rest chromatographed using hexaneethyl acetate mixture as eluent. Yield of product 20%. EFFECT: illuminated complicated operations associated with hydrolysis of chlorophyll and purification of phytol. 4 dwg
