Bicyclic oxazolidine 6, a potential precursor for the synthesis of enantiopure piperidines and indolizidines, was synthesized from (R)-phenylglycinol. A stereoselective addition of cyanide anion on this compound afforded ultimately (2S,3S)-3-hydroxypipecolic acid 9.
由(R) -苯基甘氨醇合成双环恶唑烷6,其为合成对映纯的哌啶和吲哚并咪唑的潜在前体。在该化合物上立体选择性地添加氰化物阴离子,最终得到(2 S,3 S)-3-羟基哌酸9。
