The potential of sulfimides as chiral acyl anion equivalents

Reaction of the tosyl imides 6 and 8 of 1,3-dithiane and 1,3,5-trithiane with sodium hydride and alkyl iodides in DMF yields anti alkylated products in all cases. In the case of the trithiane imide 8, both mono- and di-alkylation is observed. Preparation of cyclic sulfimide analogues of Eliel's oxathiane is shown to be problematic, but a new class of O,S-acetals, namely 4-bromophenylthiomethyl (BPTM) ethers, is introduced as a replacement for their troublesome phenylthiomethyl (PTM) analogues.

A thioether compound and its synthetic method and application (by machine translation)

The invention belongs to the technical field of sulfur-containing organic synthesis, discloses a thioether compound and its synthetic method and application. The vinyl ether compound is acetone, b of sulfur compounds, inorganic alkali and 18 - crown ether - 6 mixing, heating and stirring, in the inorganic alkali under the action of the catalyst, the reaction under air atmosphere, and then concentrated, purified made, the vinyl ether compound of molecular formula as formula (1) as shown: Wherein R1 And R2 Selected from hydrogen atom, alkyl, alkoxy, nitro, amino, hydroxy, halogen base, acyl, aryl or a heterocyclic group. The method can avoid the toxicity is relatively large of the methylene chloride and halogenated hydrocarbon such as methylene diiodide. The synthesis step is simple, convenient and easy operation, environment friendly and under a comparatively mild condition, have high conversion, the yield of the product can be as high as 96%. The thioether compound can be applied to the production of organic synthetic intermediates in the field. (by machine translation)

Cs2CO3-promoted methylene insertion into disulfide bonds using acetone as a methylene source

An efficient halogen-free Cs2CO3-promoted methylene insertion into disulfide bonds has been achieved using acetone as a methylene source under mild conditions. This method provides a convenient and practical route to dithioacetals in up to 96% yield with good functional group compatibility.
