Synthesis is a major area of organic chemistry which often requires multiple material to a target compound. A systematic way to propose a synthesis e chemistry which often requires multiple steps to convert one organic systematic way to propose a synthesis is to work backwards from the target compound to a readily available starting material. This 'retrosynthesis app arrow wie starting material. This 'retrosynthesis' approach is indicated by the within a synthesis proposal. (See Wade textbook, pg 410ff, Problem Solving...
