WebSep 28, 2024 · In addition, we aimed to develop stereoselective petasin synthesis by chiral pool approach, whereas the method of Bestman et al. developed to synthesize target molecule with the desired conformation by enzymatic optical resolution. Initially, we considered the efficient synthesis of petasin by retrosynthetic analysis (Scheme 1 b). WebFeb 28, 2024 · The paper describes the first total synthesis of natural varioxiranol A by chiral pool approach and confirmation of its absolute configuration by single-crystal X-ray analysis. The target varioxiranol A and its 4-epimer were obtained after 10 steps from single and available chiral source 1,2- O -isopropylidene-d-glyceraldehyde in an overall ...
