  A Concise Synthesis of (+)-SCH 351448

  摘要：

  yWe describe a highly convergent synthetic approach to the natural product (+)-SCH 351448 (1)-a hexane-soluble heptacoordinate monosodium salt of a C-2-symmetrical macrocyclic dilactone. Our approach implements a photochemical acylation as the key step to combine two nearly identical but orthogonal C1-C29 fragments, followed by a base-induced intramolecular acylation and deprotection to yield the natural product.

  Synthesis of the C1−C21 (C1‘-C21‘) Fragment of the Dimeric Polyketide Natural Product SCH 351448

  摘要：

  A convergent, stereoselective assembly of the C1-C21 (Cl'-C21') fragment of SCH 351448, a 28-membered bis-lactose natural product, has been developed. A highly efficient approach to this fragment assembles 75% of the carbon skeleton and all the stereochemical elements present in the natural product. In addition, an interesting boron ligand effect on the diastereoselectivity of a key aldol reaction with methyl ketone-derived enolborinates is reported.
