First total synthesis of (+)-koninginin D

A total synthesis of (+)-koninginin D (1) is described; the absolute configuration of the immediate antecedent of 1 is shown to have the configuration 7R,9S,10S by X-ray diffraction analysis.

Total synthesis of koninginin D, B and E

Total synthesis of koninginin D, E and B was described. The structures of koninginin B and F, which were deduced as C4 epimer of koninginin E and D, respectively, have been corrected.
