Heading south: An efficient approach to the FGHI southern ring system of azaspiracid-1 is disclosed. Each of the eight stereogenic centers is generated with excellent diastereoselectivity. In addition, the stereochemical outcome of the ketalization steps could be controlled by careful selection of the conditions. Teoc = 2-(trimethylsilyl)ethoxycarbonyl; TMS = trimethylsilyl; TIPS = triisopropylsilyl; Bn = benzyl. (Chemical Equation Presented).
