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 کاملGlycine methyl ester hydrochloride
THE TITLE COMPOUND [SYSTEMATIC NAME: (methoxy-carbonyl-meth-yl)ammonium chloride], crystallizes as a salt, C(3)H(8)NO(2) (+)·Cl(-), with the charged species inter-acting mutually via strong and highly directional N(+)-H⋯Cl(-) hydrogen bonds which lead to the formation of a supra-molecular tape running parallel to the c axis. Tapes close pack in the solid state mediated by multipoint recognition...
متن کاملSynthesis of 1-methyl-3-oxo-7-oxabicyclo[2.2.1]hept-5-ene-2-carboxylic acid methyl ester.
A simple and efficient method for the preparation of 1-methyl-3-oxo-7- oxabicyclo[2.2.1]hept-5-en-2-carboxylic acid methyl ester (1) is described. The first step is a highly regioselective Diels-Alder reaction between 2-methylfuran and methyl-3-bromo- propiolate. A remarkably difficult ketal hydrolysis reaction was effected by treatment with HCl, a simple reagent that was shown to be more effic...
متن کاملInsulin Methyl Ester
There is considerable experimental evidence in support of the view that, in solution, the state of molecular dispersion of insulin is dependent on the net charge of the protein (10, 6, 8). In these investigations, alterations of the net positive charge were obtained by varying the pH of the solutions, with due consideration of the effect of the specific binding affinity of the protein for anion...
