The first stereoselective total synthesis of lankanolide. Part 2

The seco-acid derivative designed by conformation calculation and lactonization experiment of model seco-acids was synthesized, and subjected to macrolactonization to afford the lactone derivative. The lankanolide was synthesized via several steps after the lactonization, and the synthetic lankanolide was confirmed to have the same physical data (NMR, mass, IR and αD) as the lankanolide prepared from lankamycin according to the reported method.

Asymmetric crotylation reactions in synthesis of polypropionate-derived macrolides: Application to total synthesis of oleandolide

Complete details of a convergent asymmetric synthesis of oleandolide (1), the aglycon of the macrolide antibiotic oleandomycin, is described. The synthesis has been achieved through the assembly and coupling of the left- and right-hand subunits 12 and 38,

Efficient strategy for the synthesis of stereopentad subunits of scytophycin, rifamycin S, and discodermolide.

[reaction: see text] An efficient, simple method has been developed for the stereocontrolled synthesis of polypropionate stereopentads in high enantio- and diastereomeric purities.
