Examination of the toluene-p-sulphonic acid-catalysed reaction of (1S,2S,3R,6R)-(+)-trans-car-2-ene epoxide with olivetol shows that, inconsistently with the accepted mechanism, (3R,4R)-(–)-o- and -p-cannabidiols are produced as well as (3R,4R)-(–)-Δ1-and Δ6-tetrahydrocannabinols. Evidence is now presented that, as in Petrzilka's reaction employing chiral p-mentha-2,8-dien-1-ols, the reacting species
对甲苯-对磺酸催化的(1 S,2 S,3 R,6 R)-(+)-反式-car-2-ene环氧与橄榄酚的反应表明,与公认的机理不一致, (3 - [R,4 - [R )- ( - ) - ø -和- p -cannabidiols产生以及(3 - [R,4 - [R )- ( - ) - Δ 1 -和Δ 6 -tetrahydrocannabinols。现在有证据表明,就像在Petrzilka的使用手性p -mentha-2,8-dien-1-ols的反应中一样,反应的物种是离域的(4 R)-p -mentha-2,8-dien-1-yl阳离子(9)。
