5-Propyl-6-(p-tolylsulfanyl)pyrimidine-2,4(1H,3H)-dione
In the title pymiridine-2,4-dione derivative, C14H16N2O2S, the dihedral angle between the six-membered rings is 66.69 (10)°. The mol-ecule is twisted about the Cp-S (p = pyrimidine) bond, with a C-S-C-N torsion angle of -19.57 (16)°. In the crystal, adjacent mol-ecules form inversion dimers through pairs of strong N-H⋯O hydrogen bonds, generating an R 2 (2)(8) ring motif. The dimers are connect...

Starting from 2,2'-dihydroxybiphenyl and an allenic ester, the title dibenzo-condensed dioxepine derivative was synthesized using a one-pot procedure.
متن کاملKanamycin 6'-acetate and ribostamycin 6'-acetate, enzymatically inactivated products by Pseudomonas aeruginosa.
The enzyme solution (S-100) was prepared by the procedure described in a previous paper.l) The inactivation was carried out at 37°C for 3 hours in the following reaction mixture : 100 mg (0.2 mmoles) of kanamycin or 91mg (0.2mmoles) of ribostamycin in 25ml of water, 4,842mg (8.0mmoles) of disodium ATP trihydrate in 100 ml of 0.8 % sodium bicarbonate, 25 mg (0.03 mmoles) of coenzyme A in 50ml of...
متن کامل5 /J,6/?-Epoxidation of 3 jß-Cholesteryl Acetate and its Analogues
The incorporation of oxygen containing groups into the steroid structure is of considerable interest in connection with the synthesis of corticosteroids and cardioactive substances. Oxidations with reagents containing hexavalent chromium have been widely used either to functionalize non-activated positions of policyclic hydro carbons [1 ], or to obtain through allylic oxidations keto derivativ...
