This review paper covers the major synthetic approaches attempted towards the synthesis of α-azido ketones, as well as the synthetic applications/consecutive reactions of α-azido ketones.

Thyroid follicles perform several functions that depend upon epithelial polarity: secretion of thyroglobulin (Tg) to the apical lumen, uptake of iodide for Tg iodination, and the manufacture of thyroid hormone for delivery to the bloodstream. In this report we examine Tg processing by thyroid epithelial monolayers cultured on porous filters. Basolateral 125I uptake resulted in thyrotropin-depen...

The diazo group has untapped utility in chemical biology. The tolerance of stabilized diazo groups to cellular metabolism is comparable to that of azido groups. However, chemoselectivity has been elusive, as both groups undergo 1,3-dipolar cycloadditions with strained alkynes. Removing strain and tuning dipolarophile electronics yields diazo group selective 1,3-dipolar cycloadditions that can b...

Molecules carrying the azido functionality are widely used as intermediates in medicinal chemistry. Pyrrolobenzodiazepines molecules with a broad range of interesting pharmacological properties. Due to wide importance azido-PBD key intermediate many synthetic pathways, this work we have investigated effect variety experimental parameters on mechanism nucleophilic substitution reaction for intro...

A series of iodine( i ) complexes were prepared and their iodination potential was tested utilising the conversion antipyrine to iodo-antipyrine, results compared, especially with respect ubiquitous Barluenga's reagent.

Radioactive iodine is currently used to label proteins as a method of investigating protein metabolism in vivo or as a tracer for studies in vitro. However, recent observations indicate that changes in the molecular characteristics of proteins after iodination may lead to an apparent increase in the turnover rate in vivo (Regoeczi, 1971 ; Krohn et al., 1972). Incorporation of iodine into protei...

Two M(II) tetranuclear complexes bridged only by azido, Mn4(N3)(7.3)Cl(0.7)L4 (1) and Co4(N3)8L4 (2) in which the four M(II) ions are precisely coplanar bridged only by six azido anions, were obtained by using 4,5-diazafluoren-9-one (L) as a corner ligand. Magnetic studies indicate that ferromagnetic coupling was conducted by the azido anions between M(II) ions. At low temperature, 1 exhibits a...
