Summary: Chemists offer two new methods to develop a way to easily replace a carbon atom with a nitrogen atom in a molecule. The findings could make it easier to develop new drugs.
The scientists pointed out that both solutions involved a bit of serendipity and invention.
"To me, this is a great example of the creativity that you need in order to make breakthroughs in chemistry," said Levin. "In both we had precipitating events that gave us a glimpse of something unusual, and that gave us a foothold we could work from."
