An Investigation on the Production of Random Copolymer with Monothiocarbonate and Trithiocarbonate Units over Cyclic Thiocarbonate via Metal-free Catalysis

Synthesis of poly(thiocarbonate)s from the copolymerization of epoxides and carbon disulfide (CS2) remains a tough challenge, due to inevitable oxygen-sulfur atom scrambling process. In this work, we utilized the oxygen-sulfur exchange reaction

NBS/DMSO-mediated synthesis of (2,3-dihydrobenzo[b] [1,4]oxathiin-3-yl)methanols from aryloxymethylthiiranes

(2,3-Dihydrobenzo[b][1,4]oxathiin-3-yl)methanols were synthesized via reactions of aryloxymethylthiiranes and N-bromosuccinimide (NBS) in DMSO under microwave irradiation. The reaction mechanism was proposed as an intramolecular aromatic electrophilic substitution of 1-bromo-2-(aryloxymethyl)thiiran-1-iums, generated from aryloxymethylthiiranes and NBS, and the subsequent DMSO nucleophilic ring opening reaction of thiiran-1-iums followed by the water displacement. The current method provides a direct and simple strategy in the efficient preparation of (2,3-dihydrobenzo[b][1,4]oxathiin-3-yl)methanols from readily available aryloxymethylthiiranes.

Facile synthesis of thietanes via ring expansion of thiiranes

Thietanes are pharmaceutically important cores of some biological compounds and intermediates of organic synthesis. Various thietanes were prepared from thiiranes via ring expansion through a reaction with trimethyloxosulfonium iodide in the presence of sodium hydride. The reaction process is a nucleophilic ring-opening reaction of thiiranes with dimethyloxosulfonium methylide, generated from trimethyloxosulfonium iodide and sodium hydride, and subsequent intramolecular displacement (cyclization) of thiolates to the dimethyloxosulfonium moiety. The current method provides a new strategy for efficient preparation of thietanes from readily available thiiranes.

Lipase-catalyzed enantiomeric separation of 1-aryloxy-3-thiocyanatopropan- 2-ols: An attempt to prepare optically active thiiranes

Opening of the epoxide ring of several arylglycidyl ethers with thiocyanato anion followed by acetylation yielded racemic mixtures of 1-aryloxy-3- thiocyanato-propan-2-yl acetates. A lipase-catalyzed hydrolysis of the acetates resulted in the separation of the enantiomers. The unstable, optically active (S)-1-aryloxy-3-thiocyanatopropan-2-ols, were converted into the corresponding 2-aryloxymethyl thiiranes, which instantly polymerized to yield the optically active oligomers.

Conversion of epoxides into 2-hydroxyethyl thiocyanates with NH 4SCN in the presense of 2,6-BIS[2-(O-amino phenoxy)methyl]-4-bromo-1- methoxybenzene (BABMB) as catalyst

A convenient and efficient procedure for the ring-opening of 1,2-epoxyethanes with ammonium thiocyanate in the presence of 2,6-bis[2-(o-aminophenoxy)methyl]-4-bromo-1-methoxybenzene (BABMB) is described. In this study, a reagent and conditions have been discovered with which the individual 2-hydroxyethyl thiocyanates can be synthesized in high yield and with more than 90% regioselectivity. Thus, several 2-hydroxyethyl thiocyanates, useful intermediates toward biological-active molecules, are easily obtained in very good yields.
