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 simple, highly efficient and environmentally benign method for the synthesis of benzyl dithiocarbamates was reported. Without addition of metal catalyst, a series of 34 benzyl dithiocarbamates were obtained in good to excellent yields by treating benzyl halides with tetraalkylthiuram disulfides in water. The protocol allows easy access to C(sp3)–S bond formation, features the advantages of easy performance, environmental friendliness, good to excellent yields, and good functional tolerance, showing potential value for the preparation of some biologically active compounds.

A new strategy for the synthesis of a variety of dithiocarbamates and thioamides has been developed employing inexpensive and readily available methylarenes under metal-free and solvent-free conditions. The approach offers a one-pot procedure and has also been extended to the synthesis of a diverse range of benzyl esters.
