  Enantioselective Total Synthesis of the Antifungal Natural Products Chlorotetaine, Bacilysin, and Anticapsin and of Related Compounds: Revision of the Relative Configuration

  摘要：

  Enantioselective and diastereoselective syntheses of the title antifungal natural products and some of their diastereoisomers are described. Key steps include the diastereoselective 1,6-addition of bislactim ether 14 and a stereoselective, deprotonation of ketone 17 using lithium (S,S)-bis(1-phenylethyl)amide as a chiral base. All natural products possess the (S)-configuration at C-1 of the substituted cyclohex(en)yl residues of the C-terminal amino acids, which contradicts the assignments in the literature. At physiological pH most of the dipeptides are instable and react by an intramolecular 1,4-addition with the formation of 6-oxoperhydroindoles.
