    摘要: Process for the preparation of a compound of formula (VII) wherein R1 is Cl, F or CF3; R2 is H, Cl, F or CF3; and R3 is C1-4 alkyl; characterized in that an olefin of formula (II) is epoxidized to give an oxirane of formula (III) which treated with alkyl-magnesium halide gives a triol of formula (IV) which is turned into an epoxide of formula (V), then treated with 1,2,4-triazole. The compounds (VII) are useful for preparing azole derivatives active as antifungal agent.

    摘要: A method for the removal of heavy metals from solutions of organic compounds by treatment with cysteine or with an N-acylcysteine is described. Organic compounds with a content of heavy metal, for example palladium, particularly low and suitable for the preparation of compounds with pharmacologic activity can be isolated from the resultant solutions.
