Convergent synthesis
In chemistry a convergent synthesis is a strategy that aims to improve the efficiency of multi-step chemical synthesis. In linear synthesis the overall yield quickly drops with each reaction step:
A → B → C → D
Suppose the yield is 50 or each reaction, the overall yield of D is only 12.5 rom A.
