The title compound, C 17 H 29 NO 6 , crystallizes with two molecules in the asymmetric unit. The independent molecules differ in the conformation of the side chain attached to nitrogen. The piperidine ring adopts a chair conformation, with the 1,3-dioxolane ring occupying an axial position.
L. gave the gas chromatogram shown below [2]. Using a GC/MS-coupling system (Varian MAT 311A), in addition to nonanone-2, the spiroketals 1-4 could be 9 identified, all of which occurred as pairs of diastereomers [3]. According to [4], authentic samples were prepared for comparison.
