The first enantiomerically pure thiadiazol-3-one 1-oxide and thiatriaza-indene 3-oxide systems chiral at the sulfur atom

Tuning the reaction pathways of phenanthroline-Schiff bases: routes to novel phenanthroline ligands

“…1,10-Phenanthroline-5,6-dione and the esters of the amino acid hydrochloride were synthesised using literature procedures. 28,29 All amino acid ester hydrochlorides used are previously reported compounds. The generalised procedure to synthesise the amino acid esters is as follows: Acetyl chloride (4.352 mL, 60.99 mmol) was added to a cold solution of the required alcohol (1.40 mol).…”
