Chiral recognition by CD-sensitive dimeric zinc porphyrin host. 1. Chiroptical protocol for absolute configurational assignments of monoalcohols and primary monoamines

A general microscale protocol for the determination of absolute configurations of primary amino groups or secondary hydroxyl groups linked to a single stereogenic center is described. The chiral substrates are linked to the achiral trifunctional bidentate carrier molecule (3-aminopropylamino)acetic acid (1, H2NCH2CH2CH2NHCH2COOH) and the resultant conjugates are then complexed with dimeric zinc porphyrin host 2 giving rise to 1:1 host/guest sandwiched complexes. These complexes exhibit exciton-coupled bisignate CD spectra due to stereodifferentiation leading to preferred porphyrin helicity. Since the chiral sense of twist between the two porphyrins in the complex is dictated by the stereogenic center of the substrate, the sign of the couplet determines the absolute configuration at this center. The twist of the porphyrin tweezer in the complex can be predicted from the relative steric sizes of the groups flanking the stereogenic center, such that the bulkier group protrudes from the complex sandwich. In certain alpha-hydroxy esters and alpha-amino esters, electronic factors and hydrogen bonding govern the preferred conformation of the complex, and hence the CD spectra.

Stereoselective synthesis of the specialized pro-resolving and anti-inflammatory mediator resolvin E1

The n-3 polyunsaturated fatty acids eicosapentaenoic acid, docosahexaenoic acid and n-3 docosapentaenoic acid, act as substrates for the biosynthesis of specialized pro-resolving lipid mediators. Resolvin E1, produced from eicosapentaenoic acid, was the first specialized pro-resolving lipid mediator reported. This oxygenated polyunsaturated fatty acid displays a plethora of interesting biological activities, and has entered initial clinical trial development programs. The Evans-Nagao aldol reaction, a stereoselective alkyne reduction and a Z-selective Wittig reaction, were utilized for the stereocontrolled synthesis of resolvin E1 presented herein. In addition, results from HPLC analysis revealed that the synthetic material matched authentic resolvin E1.

A short and practical synthesis of 2?-deoxymugineic acid (DMA) has been developed via reductive alkylation with the aldehyde intermediates. No protection of azetidine-2-carboxylic acid was required and the presence of free carboxylic acid function facilitated purification by simple acid and base extractions. Furthermore, the intermediates were conveniently purified by HPLC due to the presence of chromophoric benzyl ester protecting group(s). Hydrogenolysis of the benzyl protecting groups in the final step furnished DMA in overall good yield.
