Perilla alcohol

Epoxidation and dehydration led to 3,4-epoxycyclohexene which, on treatment with lithium isopropenylcuprocyanide gave the alcohol 539. This was then oxidized to the ketone 538. Stevens and Albizati made 538 by addition of a methylene group to the acetyl carbonyl group in 4-acetylcyclohexanone. Somewhat more interesting is their synthesis of the (/ )-isomer of 538 from (-)-perilla alcohol (536, R = H) following Scheme 54. ... [Pg.370]

Terpineol (556) has been found in Lavandula latifolia and with somewhat less evidencce, reported in Coridothymus capitatus It was synthesized by hydration of P-pinene (142) in the presence of mercury, a method due to Fdtizon and described below (perilla alcohol). ... [Pg.373]

A better method for the hydrogenation of perilla alcohol (536, R = H) to shisool (606) than the one described in Volume 4 (p, 520, Ref. 450) is using copper-chromium or copper-zinc catalyst and hydrogen. The major product at 80—150°C is said to be the cw-isomer 606, higher temperatures (up to 240°C) giving the franj-isomer. ... [Pg.380]

Perilla alcohol (232) (98%) has been prepared by treating 3-pinene epoxide (231) with HgS04 that is suspended in a water-THF mixture, extracting into ether, and treating the ethereal extract with dilute H2S04. ... [Pg.38]

Ring-opening of -pinene with iodine," and of a-pinene with a zinc-copper couple have been mentioned addition of acrolein and methyl acrylate to -pinene may also result in some ring-opened products,and so do the reactions with iodine azide, aldehydes in the presence of light, and ketones in the presence of t-butyl peroxide. Of particular interest in this respect is a paper by Julia et al., who describe the production of cis- and trans-carveols (118) from a-pinene, and perilla alcohol (388) from -pinene with retention of configuration, using benzoyl peroxide in the presence of cupric salts. ... [Pg.80]
