The asymmetric syntheses ot (2S,3S,6S)-, (2S,3S,6R)-, and (2R,3R,6S)-2,3-methano-2,6-diaminopimelic acids (7a-c) is described. The synthesis features phosphonate coupling of 13 and 14 to form the corresponding E-olefins which are subsequently cyclopropanated and deprotected under dissolving metal conditions.
描述了(2S,3S,6S)-,(2S,3S,6R)-和(2R,3R,6S)-2,3-甲基-2,6-二氨基庚二酸(7a-c)的不对称合成。该合成的特征是13和14的膦酸酯偶联形成相应的E-烯烃,随后将其环丙烷化并在溶解金属条件下脱保护。
