are synthons for the stereodivergent syntheses of pybox ligands. The trans-isomers have been synthesised previously from the corresponding bis-amides derived from pyridine-2,6-dicarbonyl dichloride, the cis-4,5-disubstituted isomers are prepared for the first time from the same aminols and dimethyl pyridine–2,6-dicarboximidate. This protocol is also suitable for the synthesis of pybox derived from
(1 R,2 S)-2-氨基-1,2-二苯乙醇和(1 R,2 S)-去氧麻黄碱是pybox配体立体发散性合成的合成子。的反式-异构体已经从由吡啶-2,6-二羰基二氯化物衍生的相应的双-酰胺预先合成的顺式-4,5-二取代的异构体,第一次从同一aminols制备和二甲基吡啶-2-, 6-二羧酸亚胺酯。该方案也适用于合成衍生自(S)-蛋氨酸和(2S)-2-氨基-2-(2'-萘基)乙醇的pybox 。
