A convenient and high-yield synthesis for N1-tritylethane-1,1,2,2-d4-1,2-diamine, a novel mono-protected ethylenediamine-C-d4, is reported. N1-tritylethane-1,1,2,2-d4-1,2-diamine was prepared in three steps from ethylene oxide-d4 in a combined yield in the range 68–76%. Also reported is a synthesis of ethylenediamine-C-d4 in two steps from 1,2-dibromoethane-d4 in a combined yield in the range 61–65%.
报告了一种便利且高效的合成N1-三苯甲基乙烷-1,1,2,2-d4-1,2-二胺的新方法,这是一种单保护的乙二胺-C-d4。N1-三苯甲基乙烷-1,1,2,2-d4-1,2-二胺通过三步从乙烯氧化物-d4制备而成,总体收率在68%至76%之间。同时,还报告了通过1,2-二溴乙烷-d4的两步合成乙二胺-C-d4,总体收率在61%至65%之间。
