The document outlines the steps taken in the total synthesis of valerenic acid, a GABAA response modulator. It involves multiple organic transformations including a Grignard reaction, silyl protection, ene-yne metathesis, deprotection, isopropenylation, acidic workup, chiral resolution, recycling, building a ring system, reduction, Wittig reaction, hydrogenation, oxidation, making an enol triflate, methylation, and hydrolysis. For each step, the document instructs the reader to assign the class of transformation, conditions, and look for nucleophilic, electrophilic, and acidic sites.
