(R)-3-Boc-4-methyl-1,2,3-oxathiazolidine 2,2-Dioxide (cas: 454248-53-4) belongs to thiazolidine derivatives. The thiazolidine ring is a cyclic N,S acetal, and most syntheses of perhydrothiazolo [3,2-a]pyridines construct the five-membered ring by condensation of aldehydes or ketones either as such or masked. Thiazolidine-2,4-dione (TZD) is an important derivative of thiazolidine with a sulfur and nitrogen atom in positions 1 and 3, and carbonyl in position 4 of the ring. These derivatives have a wide range of medicinal applications such as antiviral, antimicrobial, anticonvulsant, antiinflammatory, and antimalarial activities.Application of 454248-53-4

Synthesis of trans 8-substituted-6-phenyl-6,7,8,9-tetrahydro-3H-pyrazolo[4,3-f]isoquinolines using a Pictet-Spengler approach was written by Bailey, Andrew;Lister, Andrew;Moss, Thomas;Scott, James S.;Wu, Ye;Lamont, Scott G..

Two complementary approaches for the synthesis of trans 8-substituted-6-phenyl-6,7,8,9-tetrahydro-3H-pyrazolo[4,3-f]isoquinolines I [R = iBu, CH2CHF2, CH2CF3, (1-fluorocyclopropyl)methyl, CH2C(Me)2F; Ar = 4-BrC6H4, 5-Br-2-pyridyl, 4-Br-3-F-C6H3, 4_Br-2,6-di-FC6H2, 4-Br-2-MeOC6H3] was reported. The first method, directly from α-Me substituted indazole ethanamines, was successful but had limited substrate scope. The second method utilized a modified Pictet-Spengler cyclization reaction on an aniline substrate followed by late stage construction of the indazole ring and was more versatile in terms of substrate scope. In the experiment, the researchers used many compounds, for example, (R)-3-Boc-4-methyl-1,2,3-oxathiazolidine 2,2-Dioxide (cas: 454248-53-4Application of 454248-53-4).
