Tobacco Smoke Chemistry. 2. Alkyl and Alkenyl Substituted Guaiacols Found in Cigarette Smoke Condensate.
摘要:
A series of alkyl and alkenyl substituted guaiacols, which comprise a group of biologically and organoleptically active compounds, have been synthesized. Mass spectra and GC retention times for these have been recorded and compared with those obtained for constituents of a weakly acidic fraction of smoke condensate derived from American blend type cigarettes. On the basis of these results, 25 guaiacols have been identified, 18 of which have not been detected in tobacco smoke condensate previously.

We present herein a method for the controllable synthesis of 3-aryl-benzomorpholine and 2-aryl-benzomorpholine cycloadducts via cross-coupling/annulation between electron-rich 2-aminophenols and 4-vinylphenols.

New alkenylphenols can be obtained directly, without protecting the phenol group from the condensation reaction between phenolic aldehydes and various phosphonium salts in the presence of potassium carbonate in protic and aprotic media, using a solid-liquid phase transfer.

The invention relates to compounds, pharmaceutical compositions thereof, and methods for inhibiting sphingosine kinase and for treating or preventing hyperproliferative disease, inflammatory disease, or angiogenic disease.
Human therapeutic treatment compositions comprise at least two of a curcumin component, a harmine component, and an isovanillin component, and preferably all three in combination. The agents are effective for the treatment of human conditions, especially human cancers.
