SDS of cas: 3400-55-3. The reaction of aromatic heterocyclic molecules with protons is called protonation. Aromatic heterocycles are more basic than benzene due to the participation of heteroatoms. Compound: 2-Bromopriopionaldehydediethylacetal, is researched, Molecular C7H15BrO2, CAS is 3400-55-3, about Cyclization reactions yielding thiazolo[3,2-a]thieno[2,3-d]pyrimidines.

Thiazolothienopyrimidines I [RR1 = (CH2)4, R = R1 = Me, R2R3 = CH:CH, CMe:CH, CH:CPh] were obtained together with some II by treating I (R2 = R3 = H) with ClCH2CHO, BrCHMeCHO, BrCH2Bz, ClCH2CO2Et, or ClCH2CO2H and cyclizing with acid. I (R2R3 = CH:CMe) were obtained directly from I (R2 = R3 = H) and ClCH2COMe. I [R2R3 = (CH2)2-3] and II [RR1 = (CH2)4, R2R3 = (CH2)2] were similarly formed directly from I (R2 = R3 = H) and 1,2-dibromoethane or 1,3-dibromopropane.
After consulting a lot of data, we found that this compound(3400-55-3)SDS of cas: 3400-55-3 can be used in many types of reactions. And in most cases, this compound has more advantages.
