Benzoxazolinones. II. Synthesis of 3-vinylbenzoxazolinones and 3-vinylbenzoxazolinethione

A method has been developed for obtaining 3-vinylbenzoxazolinones and 3-vinylbenzoxazolinethione. It has been shown that it is also possible to obtain 3-methylbenzoxazolinethione by this method in good yield (76%).

226. Aminonucleosides. 3. Derivatives of 3-amino-3,5-dideoxy-D-lyxo- and D-ribo-pentoses

The 3-amino-3,5-didesoxy-1,2-O-isopropylidene-α-D -ribofuranose and -β-D -lyxo-furanose and several derivatives thereof have been prepared by hydride reduction of the corresponding oximes.     

Non-steroidal antiinflammatory agents. 3. Synthesis of 3-hydroxy-3-hydroxyphenyl-2,4-dioxo-1,2,3,4-tetrahydroquinolines

The acid-catalyzed condensation of quinisatines 5a-c or their aminals 4a-c with phenols 6a-i led to a number of 3-hydroxy-3-hydroxyphenyl-2,4-dioxo-1,2,3,4-tetrahydroquinolines 7a-s which were considered as potential antiinflammatory agents.
