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 Tailored Synthesis of Skeletally Diverse Stemona Alkaloids through Chemoselective Dyotropic Rearrangements of β-Lactones, published in 2021-06-21, which mentions a compound: 65090-78-0, Name is 2-Bromo-3-methoxypropanoic acid, Molecular C4H7BrO3, SDS of cas: 65090-78-0.

The collective synthesis of skeletally diverse Stemona alkaloids featuring tailored dyotropic rearrangements of β-lactones as key elements is described. Specifically, three typical 5/7/5 tricyclic skeletons associated with stemoamide, tuberostemospiroline and parvistemonine were first accessed through chemoselective dyotropic rearrangements of β-lactones involving alkyl, hydrogen, and aryl migration, resp. By the rational manipulation of substrate structures and reaction conditions, these dyotropic rearrangements proceeded with excellent efficiency, good chemoselectivity and high stereospecificity. Furthermore, several polycyclic Stemona alkaloids, including saxorumamide, isosaxorumamide, stemonine and bisdehydroneostemoninine (I – IV, resp.), were obtained from the aforementioned tricyclic skeletons through late-stage derivatizations. A novel visible-light photoredox-catalyzed formal [3+2] cycloaddition was also developed, which offers a valuable tool for accessing oxaspirobutenolide and related scaffolds.

There is still a lot of research devoted to this compound(SMILES：O=C(O)C(Br)COC)SDS of cas: 65090-78-0, and with the development of science, more effects of this compound(65090-78-0) can be discovered.

Compound: 2-Bromo-3-methoxypropanoic acid, is researched, Molecular C4H7BrO3, CAS is 65090-78-0, about N-Substituted amino acid N’-benzylamides: synthesis, anticonvulsant, and metabolic activities. Author is Beguin, Cecile; LeTiran, Arnaud; Stables, James P.; Voyksner, Robert D.; Kohn, Harold.

Amino acid amides (AAA) were prepared and evaluated in seizure models. The AAA displayed moderate-to-excellent activity in the maximal electroshock seizure (MES) test and were devoid of activity in the s.c. Metrazol-induced (scMet) seizure test. The AAA anticonvulsant activity was neither strongly influenced by the C(2) substituent nor by the degree of terminal amine substitution. An in vitro metabolism study suggested that the structure-activity relationship pattern was due, in part, to metabolic processes that occurred at the N-terminal amine unit.
