How the chemical complexity evolves during the process leading to the formation of a Sun and its planetary system? Is the chemical richness of a Solarlike planetary system, at least partially, inherited from the earliest stages or is there a complete chemical reset? A powerful way to answering these questions is by comparing the chemical content in young protostars and primitive bodies of the Solar System, using astrochemistry as a tool. Yet, to do so, we need to fully understand the processes that govern the chemical evolution of a molecular cloud into a young planetary system. The goal of the conference is to gather the actors of this intrinsically interdisciplinary endeavor: astronomers, chemists, and modelers. The recent huge progresses in the three areas make the time ripe for these communities to join and ride this scientific wave.
