In chemistry a convergent synthesis is a strategy that aims to improve the efficiency of multistep synthesis, most often in organic synthesis. In this type of synthesis several individual pieces of a complex molecule are synthesized in stage one, and then in stage two these pieces are combined to form the final product. In linear synthesis the overall yield quickly drops with each reaction step: Webconvergent synthesis. 合成経路を設計する方法には，1つの出発原料から直線的に経路をたどって目的物を得る「リニア合成」（linear synthesis；直線型合成）と，複数の出発 … WebMar 8, 2024 · The divergent total syntheses of complex natural products from a common intermediate have attracted enormous attention in the chemical community in the past … staple removal head days
