At my school , you need Inorganic I & II, to procede to organic I & II, then anatomy I & II to procede to biochem I and II of course your university might differ. Microbiology and Molecular Biology (at least for the pre pharm reqs) are also part of my plan.
Every university is different. But I would do general chemistry for an undergrad and get a master's in medicinal chemistry, bioanalytical chemicstry or biochemistry (all related field). Medicinal chemistry is a combination of organic chemistry, a lot of reactions to remember and draw but it refers to amino acids and proteins so you really need to know more biochem than organic chem. With organic chemistry I and II, you will be find understanding the reactions in medicinal chemistry. Hope that helps Good luck!
