Stereoselective synthesis of syn-2,7-disubstituted-4,5-oxepenes
摘要:
An efficient synthesis of the title compounds as pure enantiomers is reported. The method is based on the intramolecular trapping group of a carbocation generated by acid treatment of exo-Co-2(CO)(6)-propargyl alcohols by a stereochemically controlled secondary hydroxy a up located in a suitable chain.
