- Description:
- Okilactomycin and chrolactomycin are antitumor antibiotics isolated in 1987 and 2001, respectively. These tetracyclic natural products possess a unique 6-5 fused tetrahydropyrone-butyrolactone. The spirocenter is part of a highly functionalized cyclohexene ring, which together with the aforementioned 6-5 system compose the core of these molecules. A six carbon, 1,3-dialkyl-substituted carbon...

- Description:
- Constructing 3D objects from 2D images has been an active research area for decades. Given captured 2D information from various devices, different techniques were developed to assign 3D positions to the target object. However, methods for reconstructing a 3D model from a single 2D image remain largely manual and labor-intensive....
