c)/3. The convergent refinement (ave., max. Δ/σ=0.002,0.021) gave R1=0.1236, wR2=0.3337, and quality-of-fit=1.116. Twin models were tested for hypothetical two-fold twin axes along [100], [101], and [001], and for a hypothetical 3-fold twin axis along [010]. None of these models led to improvement of the agreement factors. The absolute configuration was established by the known stereochemistries at chiral carbon atoms C(1), C(4), C(21), and C(24). Detailed structural results have been deposited at the Cambridge Crystallographic Data Centre.

Oxetanes 4 and 7 are not enantiomerically pure compounds. They are a ca. 1:1 diastereomeric mixture due to the new stereogenic centre, which has been created at the ketalic carbon during the protection reaction of the alcohol with dihydropyran.
