complex [Mn(CO)5Br] was studied for the selective reduction of levulinic acid (LA) to 2-methyl-tetrahydrofuran (MTHF). We further studied the production of pyrrolidines via its reductive amination using silanes (phenylsilane and tetramethyldisiloxane). The results showed high efficiency and selectivity for this reaction leading to high yields using mild reaction conditions.
摘要研究了使用市售配合物[Mn(CO)5Br]的锰基催化体系将乙酰丙酸(LA)选择性还原为2-甲基-四氢呋喃(MTHF)的方法。我们进一步研究了使用硅烷(苯基硅烷和四甲基二硅氧烷)的还原胺化反应制备吡咯烷的方法。结果表明,在温和的反应条件下,该反应具有很高的效率和选择性,从而导致高收率。
