A straightforward synthesis of meso-2,6-diaminopimelic acid (DAP) meso-1 was developed from 1,4-diacetoxycyclohept-2-ene (2) via an oxidative ring cleavage. Subsequently, an enantio-divergent synthesis of (S,S)- and (R,R)-1 was performed using a homochiral monoacetate 7 available from 2 by enzymatic desymmetrization.
由1,4-二乙酰氧基环庚-2-烯(2)通过氧化环裂解开发了meso-2,6-二氨基庚二酸(DAP)meso-1的简单合成方法。随后,使用从2购得的高手性单乙酸酯7通过酶促脱对称化进行(S,S)-和(R,R)-1的对映异构合成。
