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.

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.

Reduction of CO2 into Methylene Coupled with the Formation of C-S Bonds under NaBH4/I2 System

A selective four-electron reduction of CO2 with thiophenol using NaBH4 as a reductant is described to access dithioacetals. This reaction provides a novel synthetic method for the highly selective conversion of CO2 into methylene, and a new access to molecular structures via formation of C-S bonds using CO2 as the C1 source.
