Asymmetric syntheses of the N-terminal alpha-hydroxy-beta-amino acid components of microginins 612, 646 and 680
The asymmetric syntheses of the N-terminal alpha-hydroxy-beta-amino acid components of microginins 612, 646 and 680 are reported. Conjugate addition of lithium (R)-N-benzyl-N-(alpha-methylbenzyl)amide to the requisite (E)-alpha,beta-unsaturated ester followed by in situ enolate oxidation with (-)-(camphorsulfonyl)oxaziridne (CSO) gave the corresponding anti-alpha-hydroxy-beta-amino esters. Sequential Swern oxidation followed by diastereoselective reduction gave the corresponding syn-alpha-hydroxy-beta-amino esters. Subsequent N-debenzylation (i.e., hydrogenolysis for microginin 612, and NaBrO3-mediated oxidative N-debenzylation for microginins 646 and 680) followed by acid catalysed ester hydrolysis gave the corresponding syn-alpha-hydroxy-beta-amino acids, the N-terminal components of microginins 612, 646 and 680, in good yield. An analogous strategy for elaboration of the enantiopure anti-alpha-hydroxy-beta-amino esters facilitated the asymmetric synthesis of the corresponding C(2)-epimeric alpha-hydroxy-beta-amino acids.
