Application of 3395-91-3In 2022 ,《Construction of tetralin and chromane cores by the Lewis acid promoted ring-opening cyclization of cyclopropyl methanesulfonates》 was published in Tetrahedron Letters. The article was written by Novikau, Ilya; Leushukou, Andrei; Tsiuryn, Mikita; Hurski, Alaksiej. The article contains the following contents:
Rearrangement of cyclopropyl methanesulfonates to allylic carbocations was employed for the construction of tetralin and chromate bicyclic cores. Authors found that this transformation proceeds efficiently and rapidly at room temperature in the presence of dimethylaluminum triflate serving as a non-nucleophilic Lewis acid. The reaction begins with the cyclopropanol ring-opening and follows by the Friedel-Crafts cyclization of the resulting cationic intermediate with a pendant aromatic ring. In the experimental materials used by the author, we found Methyl 3-bromopropanoate(cas: 3395-91-3Application of 3395-91-3)
Methyl 3-bromopropanoate(cas: 3395-91-3) belongs to bromides. One prominent application of synthetic organobromine compounds is the use of polybrominated diphenyl ethers as fire-retardants, and in fact fire-retardant manufacture is currently the major industrial use of the element bromine.Application of 3395-91-3
