A precursor to this molecule has its thiolactam group S-methylated by tri-methyl-oxonium fluoroborate.
A precursor to this molecule has its thiolactam group S-methylated by tri-methyl-oxonium fluoroborate. Two of this molecule's rings can be connected to form thiodextrolin via either an alkylative or oxidative precoupling followed by the addition of a tertiary phosphine. Two propionic acid side chains are attached to 6 contiguous stereocenters in a precursor to this molecule called beta-corrnorsterone. This molecule's "western half" consists of its B and Crings, which are connected by a sulfide contraction. It's not penicillin, but Dorothy Hodgkin won a Nobel Prize for determining the crystal structure of this molecule, which is based on a corrin macrocycle. The total synthesis of this compound was developed by Albert Eschenmoser and Robert Woodward. This compound's malabsorption in the small intestine causes pernicious anemia. For 10 points, name this cobalt-containing vitamin.
