Abstract
The title compound, (4S,5S,8R,10Z)-2,2,5,6,8,10- hexamethyl-4-phenyl-l,3-dioxa-6-aza-2-silacycloundec- 10-en-7-one, crystallizes with two virtually identical molecules in the asymmetric unit, each with the same absolute configuration. Bond distances and angles are normal; the closest approaches across the ring between non-bonded atoms are all greater than 3.35 Å. The amide and enol ether groups are planar to within ± 0.06 Å.
