A Simple Method for the Preparation of Cis-(3-Azido-4-Styryl)-2-Azetidinone
The synthesis of the title compound is described. Deprotection of Cis(N-Trityl-3-azido-4-Styryl)-2-azetidinone to Cis-(3-azido-4-styryl)-2-azetidinone was found to be accelerated by the special salt effect under acidic condition

متن کاملPractical preparation of 2-azido-2-deoxy-beta-D-mannopyranosyl carbonates and their application in the synthesis of oligosaccharides.
1-O-Allyloxycarbonyl (or ethyloxycarbonyl)-2-azido-2-deoxy-3-O-benzyl (or allyl, or benzoyl)-4,6-O-isopropylidene-beta-d-mannopyranose derivatives were prepared from the corresponding 2-hydroxy-beta-d-glucopyranosyl carbonates in high yields via triflation of the 2-hydroxyl group and subsequent SN2 displacement with azide ion. An N-acetyl-mannosamine-containing trisaccharide, a fragment of the ...
متن کامل4-Azido-2-chloro-6-methylquinoline
In the title compound, C(10)H(7)ClN(4), the quinoline ring system is planar [maximum deviation 0.0035 (10) Å]. The crystal structure is stabilized by van der Waals and π-π stacking inter-actions [centroid-centroid distance 3.6456 (17) Å].
متن کامل2-Azido-1-(4-methylphenyl)ethanone
In the mol-ecule of the title compound, C(9)H(9)N(3)O, the angle formed by the least-squares line through the azide group with the normal to the plane of the benzene plane ring is 46.62 (16)°. The crystal structure features C-H⋯O hydrogen bonds, which link the mol-ecules into zigzag chains running parallel to [010].
