Researchers have used single carbon atom doping to form four chemical bonds in one step. Gamma-lactams (cyclic molecules that are common in antibiotics) were easily synthetically accessible from alpha ...

Osaka, Japan – Pharmaceutical synthesis is often quite complex; simplifications are needed to speed up the initial phase of drug development and lower the cost of generic production. Now, in a study ...

Pharmaceuticals generally contain a few tens of atoms and a similar number of chemical bonds between the atoms. Thus, designing complex drug architectures from simple precursors using the techniques ...

Chemical reactions occur when elements or compounds combine and create new compounds. Elements are substances that contain only one type of atom and are represented by unique symbols on the periodic ...

Chemical Reactions: A chemical reaction is a process where the substances 8unbdergo a change in their chemical composition. The substances that enter the reaction are called reactants that are then ...

Chemical reactions make new chemicals. Atoms are rearranged during a chemical reaction, but the number of atoms does not change. Evidence of chemical reactions includes a large temperature change, ...

In the reaction, the bonds in the methane and oxygen molecule come apart, the atoms rearrange and then re-bond to form water and carbon dioxide. The little number written at the lower right after an ...
