    Total synthesis of tetronomycin
    摘要:
    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.

    L-Rhamnose is transformed to (−)-Cassine via a remarkable four step one pot reaction. The Horner–Wadsworth–Emmons [3 + 2]-1,3-dipolar cycloaddition reaction cascade is the pivotal step in this reaction sequence and makes the synthesis highly efficient.
