Baeyer?Villiger monooxygenase-catalyzed desymmetrizations of cyclobutanones. Application to the synthesis of valuable spirolactones

A series of gamma-butyrolactone derivatives, including some spiranic ones, was obtained through desymmetrization of the corresponding prochiral 3-substituted cyclobutanones via Baeyer?Villiger monooxygenase (BVMO)-catalyzed oxidation. After reaction optimization using several commercial enzymes, both antipodes of various lactones were synthesized in most cases with >90% conversion and >80% enantiomeric excess under mild reaction conditions. In some cases alcohol formation was also observed (up to 40% conversion) as an undesired side reaction due to the presence of alcohol dehydrogenases in these preparations. Selected transformations were achieved on a 100 mg scale showing the possibilities of these oxidative biocatalysts as a new source of highly interesting compounds.

Highly efficient and practical pyrrolidine-camphor-derived organocatalysts for the direct alpha-amination of aldehydes

A series of pyrrolidine-camphor-derived organocatalysts (1-4) were designed and synthesised. These organocatalysts were used for direct alpha-amination of aldehydes with dialkyl azodicarboxylates to give the desired alpha-aminated products in high chemical yields (up to 92%) and with high to excellent levels of stereoselectivity (up to >99% ee). The reactions proceeded rapidly (within 5 min) with low catalyst loading (5 mol-%) at ambient temperature. Enantioselective aminations of asymmetric alpha,alpha-disubstituted aldehydes in the catalytic system were studied, with reasonable to high stereoselectivities (up to 75% ee) being obtained. The utility of this methodology was demonstrated with the synthesis of derivatives of beta-amino-gamma-butyrolactone and a tetrasubstitutedcyclohexane-derived amino alcohol with high stereoselectivities. Transition models were proposed for the asymmetric alpha-amination reactions; they involve hydrogen-bond interactions between the nucleophilic enamine formed in situ and the nitrogen source. A highly efficient method for the alpha-amination of aldehydes with the aid of pyrrolidine-camphor-derived organocatalysts 1-4 has been developed. The alpha-aminated products were obtained in high chemical yieldsand with excellent enantioselectivities (up to >99% ee). The synthetic utility was demonstrated by the synthesis of derivatives of beta-amino-gamma- butyrolactone and a highly substituted cyclohexane.

New nodularins: A general method for structure assignment

A general method has been developed for assigning the structures of nodularin, a potent hepatotoxin, tumor promoter, and protein phosphatase inhibitor, and minor components isolated from a cultured and a bloom sample of the cyanobacterium Nodularia spumigena. It consists of (1) FABMS analysis (determination of molecular weight and molecular formula), (2) 1H NMR spectroscopy on the parent compound and chiral GC analysis of an acid hydrolyzate (identification and stereochemistry of amino acid components), (3) ozonolysis followed by NaBH4 reduction (conversion to a linear peptide), and (4) FABMS/CID/MS analyses of the linear peptide and the parent compound (sequence analysis). The method has been employed in assigning structures to three new nodularins (2-4) and can be applied to other cyclic peptides containing alpha,beta-dehydroamino acid unit(s), especially the related microcystins, cyclic heptapeptide hepatotoxins. Two nodularins, [DMAdda3]nodularin (2) and [(6Z)Adda3]nodularin (3), were obtained from a bloom sample collected from Lake Ellesmere (New Zealand), and [D-Asp1]nodularin (4) was isolated from cultured cells (strain L-575). The LD50s of 2 and 4 were 150 and 75 mug/kg (ip, mice), respectively, but 3 did not show apparent toxicity at 2.0 mg/kg.
