Sodium pyruvate as a peroxide scavenger in aerobic oxidation under carbene catalysis

NHC-Catalyzed aerobic oxidative reactions of imines and aldehydes have been developed by using sodium pyruvate as a novel and efficient peroxide scavenger. A structurally diverse set of imidates and amidines has been prepared from imines using this strategy. This general and efficient strategy features the use of sodium pyruvate as a novel and efficient peroxide scavenger and ambient air as the sole oxidant to efficiently control the NHC-catalyzed aerobic reaction pathway (selective realization of the oxidative pathway) under mild and green conditions.

The synthesis of Aminobenzothiazoles from 2,3-biaryl-5-anilino-Δ3-1,2,4-thiadiazolines

2-Amidinobenzothiazoles 4 can be prepared in high yields by a thermally-promoted rearrangement of thiadiazolium salts 1 or thiadiazolines 2. Addition of base to the rearrangement of the thiadiazolium salts can improve the yields by the prior conversion of the thiadiazolium salts to the corresponding thiadiazoline free bases. The rearrangement of the thiadiazolines may go through an electrophilic aromatic substitution or free radical pathway.

Hypervalent Iodine(III)-Mediated Solvent-Free, Regioselective Synthesis of 3,4-Disubstituted 5-Imino-1,2,4-thiadiazoles and 2-Aminobenzo[d]thiazoles

A convenient approach for the synthesis of 3,4-disubstituted 5-imino-1,2,4-thiadiazoles and 2-aminobenzo[d]thiazoles has been developed using phenyliodine diacetate (PIDA). This approach involves a metal-free oxidative C?N, N?S and C?S bond formations under neat conditions. High regioselectivity, solvent-free conditions, short reaction time and broad functional group compatibility are the notable features of this report. (Figure presented.).

Synthesis of novel heterocyclic fused 1,3-diazabuta-1,3-dienes and accompanying rearrangements in their cycloaddition reactions with ketenes: Synthesis of heterocyclic fused pyrimidinone derivatives

The reactions of 1,3-diazabuta-1,3-dienes 1 with 2-aminothiophenol have been shown to result in excellent yields of N-benzothiazol-2-yl-N′-aryl benzamidines 2. Their regioselective [4+2] cycloadditions with various ketenes are shown to yield novel benzoth

Oxidation of N-Phenyl-N'-phenylthiocarbamoylbenzamidines with Sulphuryl Chloride and Bromine

The oxidation of N-phenyl-N'-phenylthiocarbamoylbenzamidine with bromine or sulphuryl chloride yields 2,3-diphenyl-5-phenylimino-1,2,4-thiadiazoline (II) and not a benzthiazole derivative.Similar results have been observed in the case of N-phenyl-N'-(p-to
