Isochromenes, oxygen‐containing bicyclic compounds, have gained significant attention in organic synthesis due to their versatile reactivity and prominence in biologically active natural products. This review highlights recent developments in the synthesis of isochromenes, with a focus on efficient and selective methodologies. Traditional metal‐catalyzed intramolecular ring‐closure reactions have been the cornerstone for isochromene formation, but recent efforts have expanded to include new strategies that enhance functionalization and scalability. By examining key advancements in the field, this article provides a critical assessment of the current state of the art involving isochromene synthesis and its ongoing challenges.

Nitrogen‐containing molecules are used for the synthesis of polymers, surfactants, agrochemicals, and dyes. In the context of green chemistry, it is important to form such compounds from bioresource. Short‐chain primary amines are of interest for the polymer industry, like 2‐aminopropanol, 1‐aminopropan‐2‐ol, and 1,2‐diaminopropane. These amines can be formed through the amination of oxygenated substrates, preferably in aqueous phase. This is possible with heterogeneous catalysts, however, effective systems that allow reactions under mild conditions are lacking. We report an efficient catalyst Ru‐Ni/AC for the reductive amination of hydroxyacetone into 2‐aminopropanol. The catalyst has been reused during 3 cycles demonstrating a good stability. As a prospective study, extension to the reactivity of (poly)carbohydrates has been realized. Despite a lesser efficiency, 2‐aminopropanol (9% yield of amines) has been formed from fructose, the first example from a carbohydrate. This was possible using a 7.5%Ru‐36%WxC/AC catalyst, composition allowing a one‐pot retro‐aldol cleavage into hydroxyacetone and reductive amination. The transformation of cellulose through sequential reactions with a combination of 30%W2C/AC and 7.5%Ru‐36%WxC/AC system gave 2% of 2‐aminopropanol, corresponding to the first example of the formation of this amine from cellulose with heterogeneous catalysts.
