A stereoselective synthesis of a Sp dinucleotide boranophosphate with a de of > 98%, using (S)-3-hydroxyl-4-(2-indolyl)butyronitrile as chiral auxiliary, is reported. The conversion of phosphite triester to boranophosphate with BH3Me2S proceeds with retention of configuration at the phosphorus atom. The procedure may be adaptable to solid phase synthesis.
据报道,使用(S)-3-羟基-4-(2-吲哚基)丁腈作为手性助剂,对立体化学选择性地合成了DE≥98%的Sp二核苷酸硼磷酸酯。亚磷酸三酯与BH硼烷磷酸酯的转化3 Me 2 S采用在磷原子的构型保留进行。该程序可以适用于固相合成。
