Synthesis and reactivity of N -alkyl carbamoylimidazoles: Development of N -methyl carbamoylimidazole as a methyl isocyanate equivalent
A high-yielding synthesis of N-methyl carbamoylimidazole from 1,1-carbonyldiimidazole (CDI) and MeNH3Cl is described. The product is a crystalline, readily storable, water-stable compound that reacts as a methyl isocyanate (MIC) substitute. Reaction of N-methyl carbamoylimidazole in the presence of a base such as triethylamine occurs with nucleophiles such as amines, protected and unprotected amino acids, thiols and alcohols. The product N-methylureas, carbamates and thiocarbamates are obtained in good to excellent yields, with reactions occurring in either organic solvents or water. The protocol for the synthesis of N-methyl carbamoylimidazole is both scalable and general, occurring in quantitative yield at scales ranging from 300 mg to 20 g. The success of this method relies upon the reaction of CDI with the ammonium salt rather than the free amine, resulting in a significant improvement in the yield of N-methyl carbamoylimidazole. The reaction presumably involves a proton transfer from MeNH3Cl to the CDI, which results in the release of MeNH2 with simultaneous activation of the CDI as its protonated form. Other primary ammonium hydrochloride salts, including protected α-amino acid salts, give excellent yields of the corresponding N-alkyl carbamoylimidazoles and serve as alkyl isocyanate surrogates. The resultant N-alkyl carbamoylimidazoles can be converted to ureas in high yields without the formation of intermediary isocyanates.

One-pot, three-step preparation of alkyl and aryl alkylcarbamates from S-methyl N-alkylthiocarbamates
A general procedure for the synthesis of alkyl and aryl alkylcarbamates starting from the corresponding 5-methyl N-alkylthiocarbamates is described. This procedure consists of three steps that are carried out in a one-pot fashion, without isolating the intermediate N-alkylcarbamoyl chlorides or alkyl isocyanates. All the target products were obtained in high yields (16 examples, average yield 91%). To be noted is the recovery of a co-product of industrial interest, dimethyl disulfide, in a half mole amount for each mole of thiocarbamate, with complete exploitation of the reagent. The alkyl isocyanates, if required, can also be isolated in high yields. Georg Thieme Verlag Stuttgart.

An easy and efficient one-step procedure for the preparation of alkyl and aryl alkylcarbamates from S-methyl N-alkylthiocarbamates
A general, one-step procedure for the synthesis of alkyl and aryl alkylcarbamates, by the direct reaction of S-methyl N-alkylthiocarbamates with alcohols or phenols in toluene at reflux in the presence of triethylamine, is reported. All the target products were obtained in high yield (15 examples, average yield 94%) and very high purity (>99.2%). The recovery of a co-product of industrial interest, methanethiol, in an amount of one mole for each mole of thiocarbamate, with complete exploitation of the reagent, should also be noted.

Conversion of thiocarbamates to carbamates
Treatment of methyl N-methylthionocarbamate (2a) with a catalytic amount of iodine or conc. H2SO4 results in the unexpected formation of the isomer, methyl N-methylthiolcarbamate (3a) in 90% yield. This has subsequently been transformed into methyl N-methylcarbamate (4a), by sodium methoxide. A curious transformation of methyl N-methyldithiocarbamate (1a) to (4a) on prolonged treatment with sodium methoxide is also discussed.

Contra-thermodynamic trans-esteripication of carbamates by counter-attack strategy: A viable non-phosgene, non-mic route to carbamate pesticides
Treatment of methyl N-methylcarbaaate (1, R= Me) with phosphorus oxychloride and 1-naphthol results in the formation of the transesterified product, 1-naphthyl N-methylcarbamate (2, Ar=1-naphthy 1) in good yield. Similarly, ethyl N-methylthiocarbamate (5) is converted to 1-naphthyl N-methylcarbamate (2, Ar= 1-naphthyl) on treatment with phosphorus oxychloride and 1-naphthol. The mechanism of these interesting and industrially important transformations is discussed.
