Abstract: The compound (5S,6S,11 aS)-hexahydro-6-methyl-5-phenylspiro[1H,7H-pyrrolo[2,1-e][1,3,6,2]dioxazasilonine-3,1'-silacyclopentan]-7-one (1) results from the silicon-directed condensation of the prolinol-derived O-silacyclopentyl ketene N,O-acetal (2) with benzaldehyde. The five-membered pyrrolidine ring has an envelope conformation and the silacyclopentyl ring has an en-type conformation with C17 and C18 on opposite sides of the CI6--Si--C19 plane. Both of these rings appear to be disordered.
