In fact, they develop floral, slightly fruity, even metallic odor notes. The ethers of formula (I) are natural occurring compounds. We have in fact discovered that these compounds can be found in infinitesimal quantities, of the order of 50 ppm (parts per million) in the quince fruits (...
OK. So ethers, as we’ve talked about them so far, ARE pretty boring. But (and there’s always a but) – there IS a special class of ethers which is, in fact, very interesting and very reactive. If you’ve covered alkenes, you’ve seen them before – but under a different name...
Review Reports Versions Notes Abstract Oxime ethers are a class of compounds containing the >C=N-O-R moiety. The presence of this moiety affects the biological activity of the compounds. In this review, the structures of oxime ethers with specific biological activity have been collected and prese...
