4 -Longifolic acid

Oxidation of longifolene with chromic acid was first investigated by SiMONSEN and his co-workers (9, 10), who reported isolation of longi-folic and isolongifolic acids. A third acid, ot-longifolic acid was... [Pg.74]

Though the terminal oxidation of a vinylidene group in an hindered olefin to a carboxyl function by chromic acid had prior analogy (73, 81), the formation of v /-longifolic acid (128) and the ring-expanded dione... [Pg.75]

Longifolene under the usual ozonolysis conditions funishes, besides a poor yield of the expected cleavage product, longicamphenilone (9), longifolic and isolongifolic acids (126, 127) (10, 28, 81) formation of small amounts of two 5-lactones (151) has also been reported (98). When ozonation was carried out in presence of tetracyanoethylene in an effort to improve the yield of (9), though a 30% yield of (9) could be obtained. [Pg.80]
