Thietanes: Promising Small-Ring Building Blocks with Tunable Physicochemical Properties through Sulfur Oxidation-State Control
This is where four-membered-ring building blocks are particularly valuable. They are compact and rigid and can alter molecular properties through relatively small structural changes. Cyclobutanes, oxetanes, and azetidines are already widely used in drug discovery. Thietanes have historically ...
