Girolline (RP 49532) is efficiently and enantioselectively synthesized from the aldol reaction of (R)-3-chloroacetyl-4-isopropyl-1,3-oxazolidin-2-one 2 and 1-triphenylmethylimidazole-4-carboxaldehyde 3 followed by reaction with aqueous ammonia and reduction with borane. The last steps use the 2-arylazo procedure.
Girolline(RP 49532)是由(R)-3-氯乙酰基-4-异丙基-1,3-恶唑烷基-2-酮2和1-三苯基甲基咪唑-4-羧醛3的醛醇缩合反应有效和对映选择性合成的,然后与氨水并用硼烷还原。最后的步骤使用2-芳基偶氮程序。
