The structure of the title compound, C16H22O4, was determined by X-rays atT=290 K.Mr=264.320, triclinic, space groupP¯1,a=8.4857(9),b=10.0613(5),c=10.1499(7) Å,a=122.019(5)°,ß=107.049(8)°,?=74.892(9)°,Vc=696.5 Å3,Z=2,Dx=1.260 Mg m-3. MoKa radiation (graphite crystal monochromator,?=0.70926 Å),µ(MoKa)=7.03 cm-1. Final conventionalR-factor=0.058,Rw=0.088 for 2223 unique reflections and 247 variables. The structure was solved usingMultan andDirdif. The alkylation step in the synthetic preparation of clerodane-like compounds results in an equatorial position of the dioxolan group. |
