Methyl Abietate

Can be prepd by catalytic hydrogenation of methyl abietate. Hercolyn possesses excellent thermal stability. It does not corrode metals and does not develop acid on hydrolysis. Its volatility is very low (4.5mm Hg at 200°)... [Pg.112]

The diterpenoid resin acids were methylated (using diazomethane) to improve chromatographic performance. Peak identities 1, Methyl pimarate 2, Methyl sandaracopimarate 3, Methyl isopimarate 4, Methyl palustrate 5, Methyl dehydroabietate 6, Methyl abietate 7, Methyl neoabietate.

Fig (10) The iron complex (80), prepared from methyl abietate (79) is converted to compound (81) utilizing standard organic reactions. It was converted to allylic alcohol (82) by treatment with iodine and potassium bicarbonate. The ketone (83) obtained from (82) undergoes aromatization on bromination and dehydrobromination. Yielding (84) whose transformation to lactone (87) is accomplished following the similar procedure adopted for the conversion of (68) to (74). It is converted to pisiferic acid (1) by treatment with aluminium bromide in... [Pg.189]

Both Hercolyn and Abalyn combine the solvent power of abietic acid with that of a methyl ester. Thus, they may act ar. resins and as plasticizers. Both possess excellent wetting ability, even for nonporous materials such as ass and metals. Hercolyn was proposed (Refs 2 3) as a coating for NC proplnt grains Refs 1) Beil — does not list abietic acid (abi-etinsaure) or methyl-abietate 2) E.S.

Beckman rearrangement of the oxime of 7-ketodehydroabietate with phosphoric acid gives the expected lactam (50) and a decarbonylated amine (51). The dihalocarbene adduct of methyl abietate is formed " across the 7(8) double bond. The photo-oxidation of methyl isopimarate, which has a A -double bond, gives 7a-hydroxysandaracopimaric acid methyl ester. However, in the pimaric acid series both the 7a- and 14a-allylic alcohols are formed. [Pg.137]

Glaessner, Austria, 1931), ammoniacal bleached shellac (Wruble, 1933), stearic acid, carnauba wax, petrolatum, elm bark, and agar (Miller, 1935, and Worton, 1938), and abietic, oleic, and benzoic acids with methyl abietate (Eldred, 1937). Since 1940, research on enteric coatings has focused on the synthesis of resinous polymers, which are insoluble in acids, such as cellulose acetate phthalate (Hiatt, 1940) and a glycerol-stearic acid-phthalic anhydride ester (Volweiler and Moore, 1940). [Pg.957]

The n.m.r. spectra of the dihydrochloride and dihydrobromide of methyl abietate support the structure (67) rather than the 8,13-derivative previously proposed. Elimination of one mole of hydrogen chloride from the dihydrochloride affords the olefin. Treatment of the dihydrobromide with sodium ethoxide gives the diene (68). [Pg.137]

The photochemistry of the abietadienes continues to attract attention. In methanol solution, methyl abietate affords the adducts (80) and (81). On irradiation in ethanol, 8,13-cyclopropanes are also formed. However, methyl neoabietate undergoes a curious photochemical dehydrogenation to give (82). 18-Norabieta-8,ll,13-triene is obtained from the irradiation of the resin acids in acetone solution. [Pg.140]
