The enantioselective synthesis of novel C-linked spiroacetal-triazoles 10 is reported. The key step involves reaction of acetylenic spiroacetal 11 with several azides by the Copper-Catalysed Azide-Alkyne Cycloaddition (CuAAC). The biologically privileged spiroacetal scaffold 11 was prepared from silyl-protected Weinreb amide 19 using several reliable Grignard additions and a highly diastereosel...
