(Freund Publishing House Ltd, London, 2001)
A synthesis of diastereomeric (7R) 7-endo-nitrooxy-3-oxo-2,5,9-trioxabicyclo[4.3.0]nonane (4b) and (7S) 7-exo-nitrooxy-3-oxo-2,5,9-trioxabicyclo[4.3.0] (7b) is described using D-glucitol as a starting compound. Bicyclic ...
Derivative spectrophotometric method for determination of acidity constants of single step acid-base equilibria
(Elsevier Science BV, Amsterdam, 2001)
A general derivative spectrophotometric method for determination of acidity constants is developed. The method appears suitable in cases when classical spectrophotometry cannot be employed due to little differences in the ...
