Easy access to modified cyclodextrins by an intramolecular radical approach.
A simple method to modify the primary face of cyclodextrins (CDs) is described. The 6(I)-O-yl radical of α-, β-, and γ-CDs regioselectively abstracts the H5(II), located in the adjacent D-glucose unit, by an intramolecular 1,8-hydrogen-atom-transfer reaction through a geometrically restricted nine-membered transition state to give a stable 1,3,5-trioxocane ring. The reaction has been extended t...

متن کاملMODIFIED RADICAL MASTOIDECTOMY: TECHNIQUES TO DECREASE FAILURE
The aims of surgical treatment for cholesteatoma include complete removal of disease and formation of a dry, self cleaning ear in addition to hearing reconstruction. This presentation concentrates on techniques of open mastoid surgery or modified radical mastoidectomy to achieve a well-constructed cavity. This study analyzes both primary and revision mastoid surgery referred to the author. ...
متن کاملAccess to 1,2-diketones by an unusual radical cascade.
An unusual radical fragmentation of an unstrained cyclohexane structure was observed leading to complex 1,2-diketones.
متن کاملEasy access to antifungal agents.
Vulvovaginal candidiasis is a common problem; at one time or another most women experience at least one episode of this bothersome condition. For the past several years, the pharmaceutical industry has convinced women that this condition is easily treated and that they should recognize the symptoms of vulvovaginal candidiasis. Thus women have had access to a variety of intravaginal antifungal a...
