Hydration and Intramolecular Cyclization of Homopropargyl Sulfonamide Derivatives Catalyzed by Silver Hexafluoroantimonate(V): Synthesis of Structurally Diverse 2,3-Dihydro-1H-Pyrroles

We have developed an efficient, simple protocol for synthesis of structurally diverse functionalized 2,3-dihydro-1H-pyrroles by hydration and intramolecular cyclization of homopropargyl sulfonamide derivatives. Mechanistic experiments revealed that the sulfonamide nitrogen participated in the hydration reaction by chelating the Ag atom of the catalyst to assist in the formation of the hydration intermediate. The protocol accommodated a wide range of substrates and was used for a formal synthesis of (S)-nicotine. (Figure presented.).

Direct Access to Primary Amines from Alkenes by Selective Metal-Free Hydroamination

Direct and selective synthesis of primary amines from easily available precursors is attractive yet challenging. Herein, we report the rapid synthesis of primary amines from alkenes via metal-free regioselective hydroamination at room temperature. Ammonium carbonate was used as ammonia surrogate for the first time, allowing for efficient conversion of terminal and internal alkenes into linear, α-branched, and α-tertiary primary amines under mild conditions. This method provides a straightforward and powerful approach to a wide spectrum of advanced, highly functionalized primary amines which are of particular interest in pharmaceutical chemistry and other areas.

Facile preparation of 2-aryl-3-iodopyrroles with N-tosyl 4-aryl-3-butyn-1-ylamines, I2, andtBuOK

Treatment of N-tosyl 4-aryl-3-butyn-1-ylamines with I2 and K2CO3, followed by the reaction withtBuOK under mild conditions gave 2-aryl-3-iodopyrroles in good yields. The present approach is a one-pot method for the preparation of 2-aryl-3-iodopyrroles from N-tosyl 4-aryl-3-butyn-1-ylamines, which could be easily prepared from aryl iodides, N-(3-butyn-1-yl)phthalimides, and p-toluenesulfonyl chloride.

Synthesis of 3-Keto Pyridines from the Conjugated Allenone – Alkynylamine Oxidative Cyclization Catalyzed by Supported Au Nanoparticles

Recyclable supported Au nanoparticles on TiO2 catalyze the cyclization of N-propargyl or N-homopropargyl β-enaminones followed by dehydrogenation (aromatization) leading to substituted 3-keto pyridines or 4-picolines in very good yields. This pathway is in contrast to their known cyclization in the presence of Au(I) or Au(III) catalysts which provides 1,4-oxazepines, instead. The enaminones are formed in situ upon mixing a conjugated allenone or allenyl ester with the alkynylamine, thus the pyridine-forming transformation is typically a one pot process. (Figure presented.).

Cu-Catalyzed Tandem Aerobic Oxidative Cyclization for the Synthesis of 3,3′-Bipyrroles from the Homopropargylic Amines

A Cu-catalyzed method for the synthesis of 3,3′-bipyrroles from homopropargylic amines through tandem aerobic oxidative cyclization involving the formation of C-C bond has been developed. The features of this reaction are a small number of Cu catalysis and simple starting substrates. Moreover, this procedure exhibits good functional group tolerance and a series of 3,3′-bipyrroles derivatives are obtained in moderate to good yields.

Regioselective Amine–Borane Cyclization: Towards the Synthesis of 1,2-BN-3-Cyclohexene by Copper-Assisted Triazole/Gold Catalysis

The combination of triazole/gold (TA-Au) and Cu(OTf)2is identified as the optimal catalytic system for promoting intramolecular hydroboration for the synthesis of a six-membered cyclic amine–borane. Excellent yields (up to 95 %) and regioselectivities (5-exo vs. 6-endo) were achieved through catalyst control and sequential dilution. Good functional-group tolerance was attained, thus allowing the preparation of highly functionalized cyclic amine–borane substrates, which could not be achieved using other methods. Deuterium-labeling studies support the involvement of a hydride addition to a gold-activated alkyne with subsequent C?B bond formation.

Agri-Horticultural Pest Control Compositions Comprising 4-(3-Butynyl)Aminopyrimidine Derivatives

Agri-horticultural pest control compositions having outstanding control effect on pests, in particular, agri-horticultural pests, which comprise as active ingredients one or more 4-(3-butynyl)aminopyrimidine derivatives represented by the general formula [I], namely, where R1 is typically selected from among: a) phenyl c) —SiR5R6R7 (R5, R6, and R7 which may be the same or different represent a linear or branched alkyl having 1-6 carbon atoms, a linear or branched haloalkyl having 1-3 carbon atoms which is substituted by one halogen atom, a linear or branched cyanoalkyl having 1-3 carbon atoms which is substituted by one cyano group, and phenyl); d) hydropgen atom; R2 typically represents a hydrogen atom; R3 typically represents a hydrogen atom; R4 represents a hydrogen atom and one or more agri-horticultural pest control compounds selected from among agri-horticultural antimicrobial compounds, say, multi-site contact active compouns, nucleic acids synthesis inhibitory active compounds, mitosis and cell divesion inhibitory active compounds, and/or agri-horticultural insecticidal, miticidal or nematicidal compounds, say, acetylcholinesterase inhibitors, GABA-gated chloride antagonists, and sodium channel modulators. Since the 4-(3-butynyl)aminopyrimidine derivatives and the existing antimicrobial active compounds and/or insecticidal active compounds are used in admixture, the 4-(3-butynyl)aminopyrimidine derivatives which are useful as pest control agents, particularly as agri-horticultural pest control agents, need be used in smaller amounts and yet their antimicrobial or insecticidal activity can be improved.
