Paragraph 0010-0016, (2020/02/04)
In organic sulfur compounds, dialkyl amino dithiocarbamate alkyl ester plays a very important role. Researches show that dialkyl amino dithiocarbamate alkyl ester and the derivatives thereof have widebiological characteristics and pharmacological activity. For example, many studies show that the dialkyl amino dithiocarbamate alkyl ester has various activities, including anti-proliferative, anti-glaucoma, antibacterial, antifungal, breast cancer treatment and cholinesterase inhibition activities, and can be used as a myocardial imaging agent. It is known that dialkyl amino dithiocarbamate alkyl ester and the derivatives thereof can be taken as inhibitors of HIV-1 NCp7, antiviral agents, and non-flavonoid TRPV1 antagonists. Dialkyl amino dithiocarbamate alkyl ester has a wide application range, and is massively produced in the world. The invention provides a method for efficiently synthesizing dialkyl amino dithiocarbamate alkyl ester. Under the catalysis of CuI, a chiral quaternary ammonium salt and a dialkyl amino dithioformate are used for C-S cross coupling for the first time, and dialkyl amino dithiocarbamate alkyl ester is prepared. The target product is further converted andcoupled with brominated aromatic hydrocarbons to obtain high-purity enantiomer chiral thioethers. The synthesis process has the advantages of mild reaction conditions, wide universality, no toxicity or danger, high yield, wide substrate range and the like.

A straightforward, mild and efficient protocol for the synthesis of benzyl dithiocarbamates from benzyl chlorides and tetraalkylthiuram disulfides is presented. This protocol is compatible with a wide variety of electron-donating and -withdrawing substituents and enables construction of various dithiocarbamate derivatives from readily available starting materials.
