text] We have developed an efficient synthesis of the 7-deoxy zaragozicacidcore. The synthesis begins with a Feist-Bénary reaction that assembles all three carbons of the polycarboxylic acid portion of the core. This reaction is followed by highly diastereoselective aldol and dihydroxylation reactions that set the remaining stereocenters of the core. The synthesis finishes with lactol oxidation and

attempt to prepare thiazolo[4,5-d]pyrimidine-5,7-diol by the action of potassium hypobromite on thiazole-4,5-dicarboxamide revealed the instability of the thiazole portion of this condensed ring system when 2-substituents are lacking. The product obtained was bis-(4-amino-2,6-dihydroxpyrimidin-5-yl) disulphide, contrary to an earlier report. A number of thiazolo [4,5-d]pyrimidines have been prepared by cyclisation
尝试通过次溴酸钾对噻唑-4,5-二甲酰胺的作用制备噻唑并[4,5- d ]嘧啶-5,7-二醇的方法表明,当2-取代基被取代时,该稠环系统的噻唑部分不稳定。不足。与先前的报道相反,获得的产物是双-(4-氨基-2,6-二氢嘧啶-5-基)二硫化物。通过将相应的4-氨基嘧啶-5-基硫氰酸酯环化,已经制备了许多噻唑洛[4,5- d ]嘧啶。用亚硝酸对氨基噻唑并[4,5- d ]嘧啶进行脱氨基反应,得到了许多衍生物,其中之一是尿酸的类似物。
