An efficient one-pot synthesis of 2-thioxopyrimido[4,5-b]quinoline 3a,b has been accomplished from a three-component reaction of 6-aminothiouracil, cyclohexanone and aromatic aldehyde under microwave irradiation. Compound 3a,b was used as a key intermediate for the synthesis of Sand C-nucleoside analogs of types, 5-(4-fluorophenyl / 4-anisyl)-2-S-(-D-ribofuranosyl / arabinofuranosyl)-6,7,8,9-tetrahydro-3Hpyrimido[4
由6-氨基硫氧嘧啶,环己酮和芳香醛在微波辐射下的三组分反应已完成2-硫氧嘧啶基[4,5-b]喹啉3a,b的有效一锅合成。化合物3a,b用作合成5-(4-氟苯基/ 4-茴香基)-2-S-(-D-呋喃呋喃糖基/阿拉伯呋喃呋喃糖基)-6型Sand C-核苷类似物的关键中间体, 7,8,9-四氢-3嘧啶基[4,5-b]喹啉-4-酮(6a–d)和5-(4-氟苯基/ 4-茴香基)-2-S-(-D-葡萄糖/ galactopyranosyl)-6,7,8,9-tetrahydro-3H-pyrimido [4,5b] quinolin-4-one(8a–d)。还。2-肼基化合物9a,b用于合成3-(糖基)-6-(4-取代的苯基)-7,8,9,10四氢[1,2,4]三唑[4',3' :1,2] pyrimido [4,5-b] quinoline-5-(1H)-one(11a–d和13a–d)。研究了
