  [reaction: see text] The first total synthesis of (+)-phomopsidin has been achieved via a diastereoselective transannular Diels-Alder (TADA) reaction. Key steps in the synthesis include diastereoselective ynone reduction with (-)-alpha-pinene and 9-BBN, macrocyclization by E-selective intramolecular Horner-Wadsworth-Emmons (HWE) reaction, as well as carbometalation under Wipf's conditions, followed

  A total synthesis of the novel antifungal substance myxothiazol 1 isolated from the myxobacterium Myxococcus fulvus is described. The synthesis is based on elaboration of the S-E,E-diene thioamide 1 5 and the 2R S, 3S R amide aldehyde 2 5 as key intermediates, followed by conversion of 1 5 into the bis-thiazole 1 9 and a final Wittig coupling reaction between 2 5 and the salt 2 0 c leading to 7S,18S

  The first total synthesis of (+)-tetronomycin (1), a novel tetronic acid ionophore antibiotic, has been achieved through the synthesis and assemblage of the four cyclic segments 4, 5, 7, and 8. Construction of the C5-C-13 cyclohexyl portion 5 involves as the key step either a Beckmann fragmentation of the bicyclic ketone oxime 45 or an L-Selectride-mediated reductive annulation of the nona-2,7-dienoate 53. The C-14-C28 polyether fragment 6 was constructed by a BF3-catalyzed coupling reaction of the C-14-C22 allylsilane 7 and the C23-C28 tetrahydrofuran 8 which were derived, respectively, from L-ascorbic acid or (R)-3-hydroxyisobutyrate and L-rhamnal. The union of 5 and 6 by an aldol condensation, followed by photoisomerization of the derived diastereomeric alpha,beta-unsaturated esters, provided (Z)-61, which was converted to the aldehyde 63. Subsequent acylation of the tetronate 4 with 63 via an aldol reaction-oxidation sequence afforded the protected tetronomycin 64. Final deprotection provided synthetic tetronomycin, which was characterized as its sodium salt.
• 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) H-1 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, [DMAdda(3)]nodularin (2) and [(6Z)-Adda(3)] nodularin (3), were obtained from a bloom sample collected from Lake Ellesmere (New Zealand), and [D-Asp(1)] nodularin (4) was isolated from cultured cells (strain L-575). The LD50s of 2 and 4 were 150 and 75 mu g/kg (ip, mice), respectively, but 3 did not show apparent toxicity at 2.0 mg/kg.
