Mannich is well known for his discovery of a special form of amino alkylation which was named after him: the Mannich reaction.Mannich, C.; Krosche, W.: Ueber ein Kondensationsprodukt aus Formaldehyd, Ammoniak und Antipyrin. In: Archiv der Pharmazie, 1912, Bd. 250, 647–667. In 1912 Mannich was able to describe the first synthetical morphine glucoside.

The reaction now known as the Tiffeneau–Demjanov rearrangement (TDR) was discovered in two steps. The first step of occurred in 1901 when Russian chemist Nikolai Demyanov discovered that aminomethylcycloalkanes produce novel products upon treatment with nitrous acid. When this product was identified as the expanded alcohol in 1903, the Demjanov rearrangement was coined. The Demjanov rearrangement itself has since been successfully used in industry and synthetical organic chemistry.

Hofmann was a major contributor to the development of techniques for organic synthesis, which originated at Liebig's laboratory in Giessen. Hofmann and John Blyth were the first to use the term "synthesis", in their paper "On Styrole, and Some of the Products of Its Decomposition," predating Kolbe's use of the term by some months. What Blyth and Hofmann called "synthesis" enabled them to make inferences about the constitution of styrole. A subsequent paper, Muspratt and Hofmann's "On Toluidine", described some of the first "synthetical experiments" (synthetische Versuche) in the field of organic chemistry.

This intermediate can be converted into a terminal epoxide by usage of classical synthetical operations, such as introducing acetic acid or substitution reactions with tosylates. Next, a dithiane derived anion interacts to form an alcohol. The following step involves introducing an acidic sidechain on the C.9 hydroxyl group. This carboxylic, acidic side group is made of xylose and arabidose. The introduction is realized by protecting the C.29 and C.30 hydroxylgroups with respectively p-methoxybenzyl (MPM) and benzyloxymethyl (BOM), activating the sidechain with acid chloride, and subsequently replacing the C.30 protecting group with a more stable one, tert- butyldiphenylsilyl (TBDPS).
