Furans are five-membered aromatic heterocycles containing one oxygen atom that are important building blocks in organic chemistry, but also as natural products found in various natural sources, mostly in plants, algae and microorganisms. In this review, we discussed recent advances in the synthesis of furan compounds. Some classical methods have been modified and improved, while other new methods have been developed. A vast variety of catalysts was used for these transformations. In many studies, furan synthesis reaction mechanisms were also investigated and proposed.

AbstractVarious recommender systems (RSs) have been developed over recent years, and many of them have concentrated on English content. Thus, the majority of RSs from the literature were compared on English content. However, the research investigations about RSs when using contents in other languages such as Arabic are minimal. The researchers still neglect the field of Arabic RSs. Therefore, we aim through this study to fill this research gap by leveraging the benefit of recent advances in the English RSs field. Our main goal is to investigate recent RSs in an Arabic context. For that, we firstly selected five state-of-the-art RSs devoted originally to English content, and then we empirically evaluated their performance on Arabic content. As a result of this work, we first build four publicly available large-scale Arabic datasets for recommendation purposes. Second, various text preprocessing techniques have been provided for preparing the constructed datasets. Third, our investigation derived well-argued conclusions about the usage of modern RSs in the Arabic context. The experimental results proved that these systems ensure high performance when applied to Arabic content.
