An improved synthesis of arsenic-biotin conjugates

Abstract:

An amide linked conjugate of p-aminophenylarsine oxide and biotin is conveniently prepared in a one-pot procedure by the reaction of biotinyl chloride, formed in situ, with p-aminophenyldichloroarsine. The reaction of the arsine oxide-biotin conjugate with 1,2-ethanedithiol produces the stabilized dithiarsolane. These reagents are now readily available for a variety of applications.
