A new diversity-oriented synthesis pathway for the fabrication of a pyrimidine-embedded polyheterocycles library was developed for potential interactions with diverse biopolymers. Five different pyrimidine-embedded core skeletons were synthesized from ortho-alkynylpyrimidine carbaldehydes by a silver- or iodine-mediated tandem cyclization strategy. The resulting polyheterocycles possess diverse fused ring sizes and positions with potential functionalities for further modification.

Carbodiimides (R-N=C=N-R) are well-known intermediates for the preparation of a variety of N-containing compounds, including heterocycles and amide linkages. Be-cause of their high reactivity and easy availability, carbodiimides have been broadly used as building blocks in the synthesis of structurally complex and diverse heterocyclic com-pounds in multi-component reactions (MCRs). Recent advances in diversity-oriented syn-thesis with carbodiimide-based MCRs are discussed in this minireview and are classified into different sections based on the key transformation involved in the reactions, such as heteroannulation and nucleophilic addition reactions which containing metal-catalyzed re-actions, multi-component reactions, and catalyst-free reactions subsections.

Objective: In search of efficient anticancer agents, we aimed at the design and synthesis of a library of tetrasubstituted alkenes. These are structural analogues of tamoxifen, one of the widely used anticancer therapeutics.
Methods: Our small organic compound library was prepared via a chemical synthesis in the solution using the Larock three-component coupling reaction, which is known to tolerate diverse functional groups.
Palladium(II)-Catalyzed Enantioselective Ring Opening of Oxabenzonorbornadienes via Domino Aminopalladation of Alkynylanilines.

We report herein a robust enantioselective ring opening coupling of oxabenzonorbornadienes via Pd(II)-catalyzed domino cyclization of alkynylanilines, which features the formation of three covalent bonds and two contiguous stereocenters with excellent enantio- and diastereoselectivity and a broad substrate scope. The good functional group tolerance of this domino desymmetrization strategy enables efficient late-stage transformation of natural product-derived alkynylanilines. The resulting indolated dihydronaphthols could serve as a valuable platform to streamline the diversity-oriented synthesis of other valuable enantioenriched tetrahydronaphthalene derivatives.

Since antiquity, alkaloid natural products have served as medicinal ingredients that still contribute as an inspiration for the development of novel therapeutics. For the synthetic chemist, much of the importance of natural products lies in their acting as a forcing-function for the invention of new synthetic strategies and tactics for molecular assembly. With this rich history in mind, it remains an important goal for chemists to build nitrogenous structures with greater efficiency, abiding by economies of synthesis.
