Chem., 47(11), 2697-9 (English) 1983. CODEN: ABCHA6. 39903-76-9 and 56423-45-1 which are cas registry numbers are also used here. ISSN: 0002-1369. DOCUMENT TYPE: Journal CA Section: 5 (Agrochemical Bioregulators) Section cross-reference(s): 11, 30 (+)-Bottrospicatol (I) [84453-40-7] was obtained in high yield by conversion of (-)-cis-carveol [2102-59-2] by soil Streptomyces bottropensis. I had a strong inhibitory activity against the germination of lettuce seeds. I was synthesized by oxidizing carvone [6485-40-1] with m-chlorobenzoic acid, reducing the resulting 8,9-epoxycarvone [56423-45-1] with NaBH4, and treating the formed 8,9-epoxy-cis-carveol [39903-76-9] with 0.1 N H2SO4. I diastereoisomers (I and (+)-isobottrospicatol [84518-73-0]) were sepd. by SiO2 column chromatog. (-)-Isobottrospicatol [88586-13-4] was ineffective against germination of lettuce seeds. .

DOCUMENT TYPE: Patent CA Section: 74 (Radiation Chemistry, Photochemistry, and Photographic and Other Reprographic Processes) Section cross-reference(s): 30, 75 Ferroelec. smectic liq. crystals, useful in electrooptical display devices, are made from mixts. of 32 compds., 31 of which is a deriv. of a terpenoid alc., such as an optically active isomer of menthol, neomenthol, isomenthol, neoisomenthol, carveol, dihydrocarveol, isopinocamphenol, terpinen-4-ol, a-terpeneol, limonen-10-ol, borneol, isoborneol, fenchol, verbenol, camphenilol, cedrol, isolongifolol, myrthenol, perilla alc., citroellol, dihydrocitronellol, or nopol. Thus, I was prepd. (the prepn. is described) and used as a 10.8 wt.% soln. with racemic CE8 (ester) and the compn. gave a spontaneous polarization of 5.7 nC/cm2 at 5° below the smectic A-smectic chiral C transition and 8.4 nC/cm2 at 10° below the transition. .
