Crystal and molecular structure of (±)-cyclomethylenomycinA
- 15 Downloads
The structure of (±)-cyclomethylenomycinA, a penultimate synthetic precursor of the antibiotic methylenomycinA, was determined by direct methods from MoKα diffractometer data. The crystals of (±)-cyclomethylen-omycinA are orthorhombic, space groupPbca, a=15.5724(1),b=11.4415(1),c=9.5454(1)Å, andZ=8. The structure was refined toR=0.077. The chemically determined structure was confirmed. Bond distances and angles are normal and there are no unusual C-H | | | O intermolecular contacts.
