Current Organic Chemistry - Volume 11, Issue 12, 2007

With this second part of the special issue on “Synthetic Organic Chemistry”, inserted in the Volume 11, Number 12, August 2007 of Current Organic Chemistry, I close, as Guest Editor, the first year of activity, including three reviews which deal with the chemistry of sulfenic acids, and furan oxidations, and photooxygenation of non-aromatic heterocycles. The first review, written by M.C. Aversa, A. Barattucci, P. Bonaccorsi an Read More

This review provides a comprehensive survey of the literature on sulfenic acid chemistry from 1990 through June 2006, focusing the attention on salient aspects of their structures and involvement in organic processes. Even if the majority of known sulfenic acids cannot be isolated, some stable ones have been obtained, and their study helped dramatically the comprehension of chemical and physical properties of all sulfe Read More

Photooxygenation of non-aromatic heterocycles and cyclic compounds containing non-usual heteroatoms, namely silicon, germanium and tellurium has been reviewed. All three types of photooxygenation (Types I-III) can take place. Moreover the heteroatom can be frequently involved endorsing electron-transfer reactions which turn out to be the main pathways, even in singlet oxygen oxygenation. A vast collection of novel and u Read More

Oxidation reactions of several furan derivatives as effective methods for the preparation of key synthetic intermediates are reviewed. Depending on the oxidizing reagent the furan ring can be considered as a C-1 or C-4 synthon, which upon different conditions leads to 1,4-dicarbonyl compounds, carboxylic acids, pyranones or butenolides.

Tuberculosis (TB) and fungal diseases are opportunistic infections that very often complicate the immunological response in HIV-infected individuals [1-3]. During our studies on novel antimycobacterial and antifungal agents we synthesized a number of new pyrrole derivatives and among them some proved very active against both fungi and mycobacteria. Some others instead were very selective against mycobacteria only. So Read More
