A concise synthesis of both AB ring spiroisomers of the pectenotoxins is described. The nonanomeric AB spiroketal ring system of the pectenotoxins-1, -2, -3, and -6 is formed under very mild, kinetic spiroketalization conditions, along with the anomeric i

(Chemical Equation Presented) The direct kinetic formation of spiroketals from mixed ketal-alcohol precursors under acid catalysis was studied using four differently substituted systems. In all cases, the exclusive formation of the anomeric isomer was obs
