The invention is directed to methods of treating, preventing, or inhibiting a Hepatitis C viral infection in a mammal comprising containing the mammal with an effective amount of a compound of the formula: Wherein substitutions at R1, R2, R3-R12, and Y are set forth in the specification.
Dihydro-4,4-dimethyl-2,3-furandione (4e) was synthesized from diethyl oxalate, methylpropanal (1a) and formaldehyde in the presence of sodium methoxide. In a similar manner, analogs of dihydro-2,3-furandione 4 were prepared using other aldehydes.

A process for preparation of crystalline perindopril erbumine of formula (II) which exhibits the X-ray (powder) diffraction pattern like that shown in the figure. The process comprises reacting a solution of perindopril of formula (I), in a solvent selected from N, N-dimethylformamide or dimethyl acetals of lower aliphatic aldehydes and ketones with tertiary butylamine and crystallization of the erbumine salt thus obtained by heating the reaction mixture to reflux, filtering hot, cooling gradually to 20 ºC to 30 ºC, and further cooling to 0º C to 15 ºC for 30 minutes to 1 hour and finally filtering off and drying the crystals.

natural products and in epigenetic processes. MTs catalyze the methylation of heteroatoms and even of carbon atoms, which, in many cases, is a challenging reaction in conventional synthesis. However, C‐MTs are often highly substrate‐specific. Herein, we show that SgvM from Streptomyces griseoviridis features an extended substrate scope with respect to the nucleophile as well as the electrophile. Aside

A process for preparation of perindopril of formula (II) and salts thereof which is simple, safe, convenient and cost-effective. The process involves reaction of compound of formula (I), wherein X is chlorine or bromine with compound of formula (VII) wherein A signifies that the six-membered ring of the bicyclic system is either saturated or unsaturated, followed by catalytic hydrogenation to give the perindopril of formula (II).
