Some important results from the past seven years on the ring‐chain tautomerism of 1, 3‐
heterocycles are reviewed, including substituent effects on the tautomeric equilibria and …

A tetradentate fused bis-oxazolidine ligand (FOX) is used to coordinate to rhenium carbonyl.
The ligand binds in a κ3-NNN fashion to a Re (CO) 3+ fragment, giving an octahedral …

The reaction of TRIS with equivalent amounts of two carbonyl compounds is shown to afford,
diastereoselectively, the title compounds. The results are discussed as a synthetic strategy …

The behaviour of the title compounds, obtained from terephthaldicarboxaldehyde or 1, 2-
phthaldicarboxaldehyde and certain (non) chiral C-substituted serinols is discussed in terms …

Improved procedures are reported for the glycosylation of L-serine and L-threonine utilizing
activated Schiff base glycosyl acceptors, which are less expensive and more efficient …

Chloramphenicol (CAP) is a widely used broad-spectrum antibiotic. As the precursor of CAP,
chloramphenicol bases are stereochemically pure agents and could be used as resolution …

The iterative synthesis of 2, 4, 6-triamino-s-triazines (melamines), precursors and dendritic
structures, by amination of cyanuric chloride with C-1 versus C-2-substituted 2 …

In the reactions of (1R∗, 2S∗)-or (1S, 2S)-2-amino-1-phenyl-1, 3-propanediol with aromatic
aldehydes, five-component ring-chain tautomeric mixtures were formed, involving C-2 …

Multiple approaches are described for the elucidation of the stereochemistry in solution
(high‐resolution NMR spectroscopy) and in the solid state (X‐ray diffractometry) that are …

We report the first iterative and chemioselective approach towards the synthesis of highly
elaborated N‐substituted 2, 4, 6‐triamino‐s‐triazines (melamines) and precursors, by …
