: The deep eutectic mixtures (DESs), introduced as novel alternative to usual volatile organic solvents for organic transformations has attracted a tremendous attention of the research community because of their low cost, negligible vapour pressure, low toxicity, biodegradability, recyclability, insensitive towards moisture, and readily availability from bulk renewable resources. Although, the low melting mixture of dimethyl urea (DMU)/L-(+)-tartaric acid (TA) is still infancy yet much effective as it play double and triple roles such as solvent, catalyst and/or reagent in a same pot for many crucial organic transformations. These unique properties of DMU/TA mixture prompted us to provide a quick overview of where the field stands presently, and where it might be going in near future. To our best knowledge, no review dealing with the applications of a low melting mixture of DMU/TA appeared in the literature except the one published in 2017 describing only the chemistry of indole systems. Therefore, we intended to reveal the developments of this versatile low melting mixture in the modern organic synthesis since its first report in 2011 by Köenig’s team to till date. Hopefully, the present review article will be useful to the researcher working not only in the arena of synthetic organic chemistry but also to the scientists working in other branches of science and technology.

The synthesis of a labdane oxocane epoxy-alcohol is described starting from the Wieland–Miescher ketone derivative via ring closing olefin metathesis of a diene derivative, targeting the total synthesis of a brominated oxocane labdane diterpenoid isolated from Laurencia obtusa.
