The carbomates, obtained by the reaction of the azide with ethyl glycolate and ethyl lactate, were reduced with i-Bu2AlH and the reduction products were treated with formic acid to give the corresponding oxazolo[4,3,-a]isoquinolines. By this method, the thieno[3,2-c]pyridine analogues were also pepared.
由叠氮化物与乙醇酸乙酯和乳酸乙酯反应得到的氨基甲酸酯用 i-Bu2AlH 还原,还原产物用甲酸处理,得到相应的恶唑并 [4,3,-a] 异喹啉。通过这种方法,噻吩并[3,2-c]吡啶类似物也被制备。
