Synthesis of novel 2-methyl-3-triazolyl chromanone oxime etherderivatives as potential antifungal agents [PDF]
Journal of Mazandaran University of Medical Sciences, 2006 Background and purpose: Despite growing list of antifungal agents, their clinical value has been limited by their relatively high risk of toxicity, the emergence of drug resistance, and insufficiencies in their antifungal activity. This situation has led

Addition of Chloromethyl Methyl Ether to Isoprene and the Prepation of Isogeranyl Methyl Ether
Journal of Japan Oil Chemists' Society, 1975 The cationic addition of chloromethyl methyl ether to isoprene in the presence of metal halides was investigated in order to obtain the 1, 4-adduct, 1-chloro-3-methyl-5-methoxypentene-2. It was found that the addition of small amounts of ethyl alcohol caused a large increase in the yield of the adduct, especially in the case of stannic chloride ...
