In general, if the atoms that make up the ring contain heteroatoms, such rings become heterocycles, and organic compounds containing heterocycles are called heterocyclic compounds. An article called Synthesis of Cyclic Amidines by Iridium-Catalyzed Deoxygenative Reduction of Lactams and Tandem Reaction with Sulfonyl Azides, published in 2021-01-01, which mentions a compound: 4360-63-8, Name is 2-Bromomethyl-1,3-dioxolane, Molecular C4H7BrO2, Electric Literature of C4H7BrO2.
An efficient and convenient synthesis of various cyclic amidines has been achieved via iridium-catalyzed deoxygenative reduction of lactams with a silane followed by a one-pot cycloaddition reaction with sulfonyl azides. Using the novel tandem procedure, a large array of cyclic amidines bearing various sized rings were synthesized in good yields from readily available lactams. This methodol. has been successfully utilized in the late stage diversification of complex architectures bearing a lactam moiety.
