as key intermediates in the biotransformation of organic nitrates that have been used for the clinical treatment of angina pectoris for over 100 years. It has been proposed and widely accepted that a thiol would react with an organic nitrate to afford a thionitrate intermediate. However, there has been no example of an experimental demonstration of this elementary chemical process in organic systems
Alkaline hydrolysis of a thionitrate and a sulfenyl bromide bearing a bowl-type steric protection group produced a stablesulfenicacid. This provides a conclusive demonstration of these elementary...

A novel m-terphenyl-based steric protection group (Bpq group) bearing a dendrimer-type framework was designed and successfully applied to the stabilization of the corresponding N-thiosulfinylaniline and arenesulfenyl iodide. The Bpq group was found to provide a very inert environment for the reactive functionality embedded in its clef. (C) 2001 Elsevier Science Ltd. Ail rights reserved.
Syntheses and Structures of Stable Sulfenyl Iodides Bearing Novel Bowl-Type and Dendrimer-Type Substituents
Arenesulfenyl iodides with unprecedented.stability were synthesized by iodine oxidation of the corresponding arenethiols bearing bowl-type and dendrimer-type substituents. X-ray crystallographic analysis established their monomeric structures.
