Reactions catalyzed within inorganic and organic materials and at electrochemical interfaces commonly occur at high coverage and in condensed media, causing turnover rates to depend strongly on interfacial structure and composition, 19982-07-1, Name is N-(3,5-Dimethyladamantan-1-yl)acetamide, SMILES is CC(NC12CC3(C)CC(C2)(C)CC(C3)C1)=O, in an article , author is Labrum, Nicholas S., once mentioned of 19982-07-1, HPLC of Formula: https://www.ambeed.com/products/19982-07-1.html.
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.
