(±)-cis-1-(3-Hydroxymethyl-1-indanyl)-1,2,3,4-tetrahydropyrimidine-2,4-dione (1) was synthesised in two steps and with an overall yield of 51% from (±)-cis-3-amino-1-indanylmethanol (4) and 3-ethoxy-2-propenoyl isocyanate (3). The isocyanate 3 was prepared in 76% overall yield by reacting silver cyanate with 3-ethoxy-2-propenoyl chloride (2), which was obtained in one pot from ethyl vinyl ether and oxalyl chloride. The aminoalcohol (4) was prepared from phenylsuccinic anhydride in four steps.
(±)-顺式-1-(3-羟甲基-1-茚基)-1,2,3,4-四氢嘧啶-2,4-二酮(1)是由(±)-顺式-3-氨基-1-茚基甲醇(4)和 3-乙氧基-2-丙烯酰异氰酸酯(3)分两步合成的,总收率为 51%。异氰酸酯 3 是通过氰酸银与 3-乙氧基-2-丙烯酰氯 (2) 反应制备的,总收率为 76%,后者是由乙烯基乙醚和草酰氯一锅煮制得的。氨基醇 (4) 由苯基丁二酸酐分四步制备而成。
