Synthesis of the C1'-C11' oxazole-containing side chain of leucascandrolide A. Application of a Sonogashira cross-coupling.

An efficient, convergent synthesis of the C1'-C11' side chain (3) of leucascandrolide A (1) has been achieved. The key bond connection is made through the use of a palladium(0)-catalyzed Sonogashira cross-coupling between trifloyl oxazole (4) and alkynylmetal species (5).

[4 + 2]-Annulations of chiral organosilanes: Application to the total synthesis of leucascandrolide A

Complete details of an asymmetric synthesis of leucascandrolide A (1) are described. The synthesis highlights the use of two diastereoselective [4 + 2]-annulations for the assembly of the functionalized bispyranyl macrolide 3. An efficient assembly and un
