A novel method for the preparation of 2-carboxyl-3-aryl quinoline derivatives from anilines, ethyl glyoxalate and enol ethers as phenylacetaldehyde surrogates is reported. The three-component coupling reaction occurs rapidly under mild conditions in dichloromethane catalysed by TFA. The method allows a more direct access to 3-aryl quinolines, sidestepping issues encountered with phenylacetaldehyde
An Aromas kit uses containers of certain discrete molecules to provide odors suitable for an olfactory education of wine properties. The disclosed molecules may be found within certain wines and provide a useful olfactory reference when smelling a finished wine sample, even when the wine sample contains a myriad of other conflicting or competing molecule smells.
Compounds of the formula ##STR1## are disclosed. They possess angiotensin converting enzyme inhibition activity and diuretic activity and are therefore useful as antihypertensive agents.
公式为##STR1##的化合物已被披露。它们具有抑制血管紧张素转化酶和利尿作用,因此可用作降压剂。
