Stereoselective total synthesis of antimicrobial marine metabolites ieodomycin A and B have been accomplished starting from commercially available 4-pentyn-1-ol featuring strategic application of the Negishi reaction, Kumada coupling, and Crimmins acetate aldol. This revises the proton NMR spectra of ieodomycin

New solvent-assisted mechanistic routes were located for the (THF)W(CO)5-promoted endo- and exo-cycloisomerization of 4-pentyn-1-ol using the B3LYP/6-31G (with the LANL2DZ relativistic pseudopotential for W) theory level. A mixed model was used by explicitly including a THF molecule as a component
