2) 2,4-oxadiazoline
2,4-噁二唑啉
1.
Synthesis and Calm Activity of 3-(4-β-D-Allopyranosyloxyphenyl)-4-aryl-5-aryl-1,2,4-oxadiazoline;
3-(4-β-D-吡喃阿洛糖苷-苯基)-4-芳基-5-芳基-1,2,4-噁二唑啉的合成及其镇静活性的研究
3) 1,3,4-oxadiazoline
1,3,4-噁二唑啉
1.
Condensation of 5 with aromatic aldehydes gave corresponding hydrazones 6, then cyclization of 6 in Ac2O afforded 1,3,4-oxadiazolines 7a～7f.
以化合物4为原料在不同条件下, 合成了一系列新的1,3,4-噁二唑啉(7), 1,2,4-均三唑的Mannich碱衍生物 10a～10f, 11a～11f, 12a～12f。
4) 3,4-oxadiazoline
3,4-噁二唑啉
1.
A series of 1,3,4-oxadiazoline derivatives 3a～3e were obtained from 1,6-dihydro-6-pyridazi-none-3-carbonyl aromatic aldehyde hydrozones 2a～2e by the cyclization with acetic anhydride, and 4-thiazolidinones 4a～4e were also derived from 2a～2e with mercaptoacetic acid in DMF.
再将2a～2e与乙酸酐作用,合环得到一系列含有1,3,4-噁二唑啉环的衍生物3a～3e;在DMF中用HSCH2COOH合环,得到含有4-噻唑烷酮的衍生物4a～4e。
