Various isomers of C6-methyl-containing chiral 3,4-dideoxy furanoid sugar amino acids were synthesized following a common strategy, in which the C2 and C6 chiral centres were derived from the chiralities of the two starting materials, glyceraldehyde acetonide and N,N-dibenzylalaninal, respectively, and the C5 centre was fixed by standard diastereoselective transformations.
按照共同的策略合成了各种含C6-甲基的手性3,4-二脱氧呋喃糖氨基酸异构体,其中C2和C6的手性中心来源于两种原料的手性:甘油醛丙酮化物和N,N -二苄基丙氨酸分别通过标准的非对映选择性转化固定C5中心。
