TRANSFORMATION OF 2-BENZOYLAMINO-1-(?-NAPHTHYL)PROPAN-1-OL INTO 4-METHYL-1-PHENYL BENZO[f] ISOQUINOLINE RATHER THAN ITS 3-SUBSTITUTED ISOMER
The necessary conditions to transform hydroxyamide (1) and 2-oxazolines (2, 3) into 3- or 4-methyl benzo[f] isoquinolines (4, 5) has been established. The mechanism of these reactions has been proposed claiming the existence of the protonated 2-oxazoline (6) and the styrylamides (7) as intermediates.
متن کاملCrystal structure of (Z)-1-phenyl-3-styrylundeca-2-en-4,10-diyn-1-ol
The mol-ecule of the title compound, C25H24O, obtained by acid-catalysed 1,3-migration of an alcohol group, is T-shaped. The planes of the two phenyl rings are inclined to one another by 81.9 (2)°. In the crystal, mol-ecules are linked by O-H⋯O hydrogen bonds, forming chains along [001].
متن کاملMicrowave Assisted Enzymatic Kinetic Resolution of (±)-1-Phenyl-2-propyn-1-ol in Nonaqueous Media
Kinetic resolution of 1-phenyl-2-propyn-1-ol, an important chiral synthon, was studied through trans-esterification with acyl acetate to investigate synergism between microwave irradiation and enzyme catalysis. Lipases from different microbial origins were employed for the kinetic resolution of (R/S)-1-phenyl-2-propyn-1-ol, among which Candida antarctica lipase B, immobilized on acrylic resin (...
متن کامل2-(2-Hydroxy-2-phenylethyl)-1-methylcyclopropan-1-ol
The asymmetric unit of the title compound, C(12)H(16)O(2), contains two independent mol-ecules in which the dihedral angles between the benzene and cyclo-propane rings are 75.9 (3) and 76.3 (3)°. In the crystal, the mol-ecules are connected by O-H⋯O hydrogen bonds into a three dimensional supra-molecular structure.

A new 2-[(4-substituted-phenyl-3-chloroazetidin-2-one)-5-(2'-methylamino 4-phenyl-1', 3'-thiazolyl-]-1, 3, 4-thiadiazoles, 5(a-n) were synthesized from 2-substituted-benzylideneamino-5-[2'-methylamino-4'-phenyl-1',3'-thiazolyl]-1,3, 4-thiadiazole, 4(a-n) using 2-amino-4phenyl-1, 3-thiazole as a starting material. The synthesised compounds have been screened in vitro for their antimicrobial acti...
