Nagaoka, Toshinori; Umezu, Ken-ichi; Kouno, Kenji; Yoshida, Satoshi; Ishiguro, Yukio; Ando, Tadao (Faculty Applied Biological Science, Hiroshima University, Higashi-Hiroshima 739, Japan). Plant Growth Regulation, 20(3), 295-302 (English) 1996 Kluwer. CODEN: PGRED3. ISSN: 0167-6903. DOCUMENT TYPE: Journal CA Section: 11 (Plant Biochemistry) Section cross-reference(s): 60 Water exts. of the compost produced from activated sludge and coffee residue were found to be selectively inhibitory to seed germination of some legumes. Germination rate of white clover (Trifolium repens L.), red clover (Trifolium pratense L.) and alfalfa (Medicago sativa L.) seeds were reduced to 2, 29 and 73% of the control, resp., by water exts. of the compost (20 g l-1). However, the exts. did not show any inhibition to seed germination of sorghum (Sorghum bicolor Moench), African millet (Eleusine coracana Gaertn.), and Komatsuna (Brassica rapa L.) at the same concn. The inhibitors in the compost exts. were sepd. 5807-30-7 and 51-39-8 are cas registry numbers of chemicals which are used as reagents here. buy ion-exchange chromatog. and reverse-phase high performance liq. chromatog. (HPLC) and the inhibitory activities of seed germination were tested with whit clover seeds. Five inhibitors were isolated and identified as 3,4-dichlorophenylacetic acid, 3,4-dichlorobenzoic acid (3,4-DCB), 3,4,5-trichlorophenylacetic acid, 3,4,5-trichlorobenzoic acid and mono-2-ethylhexylphthalate by 1H-, 13C-NMR spectroscopy and mass spectrometry. The inhibitory activities of some authentic chems. of the inhibitors and the related compds. were compared. The results indicated that the main inhibitor in the compost could be 3,4-DCB, which was contained at the concn. of 6.58 mg kg-1 compost and showed the strongest inhibitory effect on seed germination of white clover among the tested compds. .

Thus, cyclohexane epoxide was treated with 3-pyrroline and the resulting pyrrolinylcyclohexanol was esterified with MeSO2Cl. The ester was treated with MeNH3 to give cyclohexylamine (±)-II. This was resolved by crystn. of its di-p-toluoyl-d-tartrate salt and (+)-II was acylated with 3,4-Cl2C6H3CH2COCl to give [1S-(1a,2b)]-(-)-III. I are analgesics, the most effective having an ED50 < 10 mg/kg in the rat tail flick test. ..
