Action of POCls and HCl on 1-0-acetyllycorine gave, quantitatively, O-acetyllycorine-chlorohydrin, which was convertible, in good yield, to lycorene-a-oxide and so-called lycorine-cis-chlorohydrin. The configuration of the latter compound was revised establishing as tram by a single crystal X-ray a

In the previous papers, 1,2) we proposed the structures of coriolin, coriolin B and C based on spectroscopic analysis, biogenetic consideration and chemical transformations. We should revise these structures based on new evidences. In this paper we report the structures and stereochemistry as pres
A stereoselective total synthesis of the proposed structure of kaitocephalin (1) was accomplished starting from L-proline and D-and L-serines. However, its 1 H NMR spectral data and retention time on HPLC were not identical with those of authentic natural kaitocephalin. The revised stereochemistry o
