Synthesis of the C1-C21 domain of azaspiracids-1 and -3

An efficient synthesis of the C1-C21 fragment of azaspiracids-1 and -3 is described. This features a Nozaki-Hiyama-Kishi reaction to couple the AB and CD ring precursors and formation of the THF-fused ABCD trioxadispiroketal system under thermodynamic conditions.
