Abstract

The 5 and 6-isomers of O-(fluoresceinylmethyl)hydroxylamine reacted with a representative sample of oxo-steroids (6-oxoestradiol, estrone, norethindrone, cortisol, progesterone, and digitoxin-dialdehyde) to produce O-(fluoresceinylmethyl)oxime conjugates in a single step in 24-84% yield after preparative high performance liquid chromotography.
