An enantioselective synthesis of the spirotetronate subunit of kijanolide
摘要:
The Diels-Alder adduct 11 of alpha-bromoacrolein and triene 9 was converted to spirotetronate 21 through a sequence involving Pummerer rearrangement of the derived sulfoxide 16, oxidation of the resulting aldehyde 17, and Dieckmann cyclization of the diester 19 followed by in situ quench with MOMCl.
