A short synthetic route to (−)-and (+)-bulgecinine, the amino acid moiety of the bulgecins was achieved from the readily available nonchiral pool starting material cis-2-butene-1,4-diol in which a Claisen orthoester rearrangement and a Sharpless asymmetric dihydroxylation were used as the key steps.
从容易获得的非手性化合物池起始原料顺式-2-丁烯-1,4-二醇(其中的Claisen原酸酯重排)实现了到(-)-和(+)-bulgecinine(bulgecins氨基酸部分)的短合成路线关键步骤是采用Sharpless不对称二羟基化反应。
