Abstract
An efficient and convenient strategy has been successfully developed for the preparation of novel hydroxylated alkaloid derivatives (also called fused multicyclic iminosugars) from p-toluenesulfonylated sugars through a Pictet-Spengler-type mechanism. This method is highly stereoselective, does not require metal catalysts, and capable of conducting gram level reactions (with a 53% yield). Some of such iminosugars had an intermediate antiproliferative effect on HCT116 tumor cells.

Yang DS, Xiang JC, Wu AX. Recent advances in the synthesis of N-heterocycles from α-amino acids mediated by iodine. Chem Commun (Camb) 2024.

Abstract
The synthesis of N-heterocycles has received extensive attention from scientists considering their important role in organic synthesis, pharmaceuticals, and materials chemistry. α-Amino acids (α-AAs), both natural and non-natural, are structurally diverse, containing basic amino groups, acidic carboxyl groups, and various side-chain R groups in a single molecule. Given their structural properties and wide range of sources, they have undoubtedly become suitable synthetic building blocks for organic synthesis. However, conventional transformations of amino acids (AAs) focus on the amino and carboxyl groups independently. Conversions for these two prominent functional groups generally do not affect both their alpha positions and their branched chains. Over the past decade, with the application of iodine (I2) in the field of heterocyclic synthesis, the use of α-AAs for diverse construction of complex N-heterocyclic structures has gained increasing attention. This synthetic strategy relies on the I2-mediated Strecker degradation, which introduces α-AAs as electrophilic carbon species into the domino reaction sequence via decarboxylation and deamination processes. In this review, we have summarized recent advances in this emerging area.

Abstract
An array of pyrrolo[1,2-a]quinoxaline derivatives were achieved with moderate to good yields via the electrochemical redox reaction, which includes the functionalization of C(sp3)-H bonds and the construction of C-C and C-N bonds. In this atom economic reaction, THF was used as both a reactant and a solvent, and H2 was the sole by-product.

Abstract
An electrochemical method was developed to accomplish the reagentless synthesis of 4,5-disubstituted triazole derivatives employing secondary propargyl alcohol as C-3 synthon and sodium azide as cycloaddition counterpart. The reaction was conducted at room temperature in an undivided cell with a constant current using a pencil graphite (C) anode and stainless-steel cathode in a MeCN solvent system. The proposed reaction mechanism was convincingly established by carrying out a series of control experiments and further supported by electrochemical and density functional theory (DFT) studies.
