Desoxyhemigossypol 6-methyl ether
THE TITLE SESQUITERPENE [SYSTEMATIC NAME: 6-methoxy-10-methyl-7-(propan-2-yl)-2-oxatricyclo[6.3.1.0(4,12)]dodeca-1(11),4,6,8(12),9-pentaen-5-ol], C(16)H(18)O(3), was isolated from pathogen-infected stele tissue of Gossypium barbadense. There are two mol-ecules in the asymmetric unit and the dihedral angle between their naphtho-furan systems is 86.48 (2)°. In the crystal, O-H⋯O hydrogen bonds be...
متن کاملMethyl-n-propyl ether.
ME T H Y L N P R O P Y L ETHER is an isomer of di-ethyl ether and possesses the formula CHs-O(CHI)J-CHJ. The physical properties of the two drugs are similar, and the vapour pressure curve of methyl-n-propyl ether is such that it may be used in the Oxford Vaporizer No. 1 without any alteration in the calibration of the instrument (see Figure). Methyl-n-propyl ether has a very unpleasant pungent...
متن کاملThe reaction of protonated dimethyl ether with dimethyl ether: temperature and isotope effects on the methyl cation transfer reaction forming trimethyloxonium cation and methanol.
Fourier transform ion cyclotron resonance mass spectrometry has been used to study the temperature and deuterium isotope effects on the methyl cation transfer reaction between protonated dimethyl ether and dimethyl ether to produce trimethyloxonium cation and methanol. From the temperature dependence of this bimolecular reaction it was possible to obtain thermodynamic information concerning the...
متن کاملLacinilene C 7-methyl ether
The title compound, C16H20O3 [systematic name: 1-hy-droxy-7-meth-oxy-1,6-dimethyl-4-(propan-2-yl)naphthalen-2(1H)-one], is a sesquiterpene isolated from foliar tissues of the cotton plant and is of inter-est with respect to its anti-bacterial properties. Its phenyl ring is ideally planar, and the maximum of deviation in the second ring is 0.386 (3) Å. The hy-droxy group and the methyl group are...
متن کاملAlternariol 9-O-methyl ether
The title compound (AME; systematic name: 3,7-dihy-droxy-9-meth-oxy-1-methyl-6H-benzo[c]chromen-6-one), C(15)H(12)O(5), was isolated from an endophytic fungi Alternaria sp., from Catharanthus roseus (common name: Madagascar periwinkle). There is an intramolecular O-H⋯O hydrogen bond in the essentially planar mol-ecule (r.m.s. deviation 0.02 Å). In the crystal, the molecule forms an O-H⋯O hydrog...
