corresponding bromo or iodo analogues by using lithium dibutyl(isopropyl)magnesate(1-) and lithium chloride under noncryogenic conditions. The procedure was optimized in terms of the choice between two magnesates and the presence or absence of lithium chloride in the reaction medium. pyridines - magnesium - lithium - organometallic reagents
使用二丁基(异丙基)镁酸锂(1-)和相应的溴或碘类似物制备在3-,5-或6-位官能化的2-甲氧基吡啶和在3-位官能化的2,6-二甲氧基吡啶。非低温条件下的氯化锂。根据在两种镁酸盐之间的选择以及反应介质中氯化锂的存在与否,对程序进行了优化。 吡啶-镁-锂-有机金属试剂
