Chen, Yu; Panek, James S. published their research in Tetrahedron in 2021. The article was titled 《Highly regio- and diastereoselective synthesis of bis-triazolines》.SDS of cas: 6630-33-7 The article contains the following contents:
A highly stereo- and regioselective homodimerization of chiral azido-esters was achieved by a 1,3-dipolar cycloaddition on chiral (E)-Me 4-azido-6-methoxy-5-methyl-6-phenylhex-2-enoates. Both 4,5-syn and 4,5-anti allylic azides could be used effectively to access corresponding bis-triazoline dimers such as I [X = 2-Br, 2-I, 3-Br; n = 0, 1] by this reproducible method. Structural conformation of a representative dimer was established by X-ray crystal anal. The experimental process involved the reaction of o-Bromobenzaldehyde(cas: 6630-33-7SDS of cas: 6630-33-7)
o-Bromobenzaldehyde(cas: 6630-33-7) is used in L-threonine aldolase-catalyzed enantio/diastereoselective aldol reactions.SDS of cas: 6630-33-7It is a key starting material in the total synthesis of an anticancer agent, (-)-taxol.
