PROCESSES FOR PREPARING 4-METHYL-5-NONANONE AND 4-METHYL-5-NONANOL

The present invention provides a process for preparing 4-methyl-5-nonanone of the following formula (3): the process comprising at least a step of subjecting 2-methylpentanoic anhydride of the following formula (1) and an n-butyl nucleophilic reagent of the following general formula (2) in which M represents Li, MgZ1, or ZnZ1, wherein Z1 represents a halogen atom or an n-butyl group, to a nucleophilic substitution. reaction Coproduce 4-methyl-5-nonanone (3), as well as a process for preparing 4-methyl-5-nonanol of the following formula (5), the process comprising at least steps of preparing 4-methyl-5-nonanone; and subjecting the obtained 4-methyl-5-nonanone and a reducing agent to a reduction reaction to produce 4-methyl-5-nonanol (5).

NOVEL SULFONIMIDOYLPURINONE COMPOUNDS AND DERIVATIVES FOR THE TREATMENT AND PROPHYLAXIS OF VIRUS INFECTION

The present invention relates to compounds of formula (I), wherein R 1, R2 and R3 are as described herein, and their prodrugs or pharmaceutically acceptable salt, enantiomer or diastereomer thereof, and compositions including the compounds and methods of using the compounds.

Friedel-Crafts Reaction of 2-Methylfuran with Saturated and α,β-Unsaturated Acid Anhydrides

2-Methylfuran (5) reacts with the saturated acid anhydrides 16 - 26 in the presence of SnCl4 to give the 2-acyl-5-methylfurans 37 - 47 selectively.The unsaturated anhydrides 27 - 32, however, yield mixtures which only in the case of senecioic acid anhydride (29) contain the respective primary product 48.Subsequent reactions lead to the addition products 55 (from 27) and 56 (from 29), and to (E,Z)-mixtures of their enol esters 57 - 62 which could partially be separated and assigned. - The olfactory properties of 2, 37 - 48, 50, 52, and 53 were investigated.
