Aldolases are key biocatalysts for stereoselective C-C bond formation allowing access to polyoxygenated chiral units through direct, efficient, and sustainable synthetic processes. Aldol reaction involving unprotected hydroxypyruvate and an aldehyde...

Studies of rare ketoses have been hampered by a lack of efficient preparation methods. A convenient, efficient, and cost‐effective platform for the facile synthesis of ketoses is described. This method enables the preparation of difficult‐to‐access ketopentoses and ketohexoses from common and inexpensive starting materials with high yield and purity and without the need for a tedious isomer separation

Compounds of the structure ##STR1## where R.sup.1 is alkyl of one to four carbon atoms and R.sup.2 is selected from (a) alkenyl of one to four carbon atoms, (b) ##STR2## (c) ##STR3## and (d) ##STR4## are potent inhibitors of lipoxygenase enzymes and thus inhibit the biosynthesis of leukotrienes. These compounds are useful in the treatment or amelioration of allergic and inflammatory disease states.

approach without changing the charge of the peptides. The multicomponent stapling was conducted in solution by linking Nϵ‐MeLys or Orn side‐chains, positioned at i, i+7 and i, i+4, with aryl tethers, while hydroxy carbonyl moieties were introduced as exocyclic fragments. The good efficiency and diversity oriented character of these methods show prospects for peptide drug discovery and chemical biology.
