Abstract A facile way to introduce CF 3 groups on a large variety of secondary amines has been developed, avoiding expensive and hazardous reagents. The advantage the method could be demonstrated by obtaining crystalline tert ‐butyl 4‐(trifluoromethyl)piperazine‐1‐carboxylate, compound that previously only had obtained as an oil. major problem is extreme sensitivity these compounds towards mois...

Automatic catheter and guidewire segmentation plays an important role in robot-assisted interventions that are guided by fluoroscopy. Existing learning based methods addressing the task of or tracking often limited scarcity annotated samples difficulty data collection. In case deep methods, demand for large amounts labeled further impedes successful application. We propose a synthesize segment ...
