摘要

beta-lactams have attracted a significant attention due to their potential biological activities and wide variety of synthetic applications. Developing novel and efficient methods for construction of functionalized beta-lactams has been the subject of a number of papers in recent years. N-Propargyl amines/amides are one of the most specific class of alkynes having diverse reaction patterns. It is well known that they can undergo a number of cyclization reactions to produce various significant nitrogen containing heterocycles. This review surveys literature methods for the synthesis of highly substituted beta-lactams from simple and easily available N-propargyl amine/amide derivatives from 1991 to 2017.

Synthesis of Thiazole-2(3H)-ones via [3,3]-Sigmatropic Rearrangement/5-exo-dig Cyclization of N-Propargylamines

Bipin Kumar Behera, Sudip Shit, Subhamoy Biswas, Anil K. Saikia

Summary: An efficient methodology for the synthesis of di- and trisubstituted thiazol-2(3H)-ones from N-propargylamines and silver(I) trifluoromethanethiolate has been developed. The reaction proceeds through [3,3]-sigmatropic rearrangement/5-exodig cyclization of N-propargylamines. The starting material can be easily prepared via the A3-coupling reaction of amines, aldehydes, and alkynes. The methodology can also be extended to the synthesis of thiozole-2(3H)thione derivatives, and the photophysical properties of some synthesized compounds have been studied.

Selective 5-Exo-Dig versus 6-Endo-Dig Cyclization of Benzoimidazole Thiols with Propargyl Alcohols

Tales A. C. Goulart, Ana M. S. Recchi, Davi F. Back, Gilson Zeni

Summary: The Lewis acid-promoted cyclization reaction of benzomidazole thiols with propargyl alcohols for the selective synthesis of benzoimidazolo thiazines and benzothiazolo imidazoles is described. The reaction is regioselective and controlled by the choice of solvent. The best reaction conditions were determined through systematic study, resulting in the formation of six-membered benzoimidazolo thiazines using boron trifluoride etherate and dichloromethane as the solvent, and five-membered benzothiazolo imidazoles using the same starting material and reagents with dimethylformamide as the solvent. The proposed mechanism of the cyclization reaction is based on experimental results and control experiments.

Highly regioselective and diastereoselective synthesis of novel pyrazinoindolones via a base-mediated Ugi-N-alkylation sequence

Maryam Tajik, Morteza Shiri, Faiq H. S. Hussain, Yazdanbakhsh Lotfi Nosood, Behnaz Baeiszadeh, Zahra Amini, Rahman Bikas, Anna Pyra

Summary: An efficient base-mediated/metal-free approach was developed for the synthesis of 1-oxo-1,2,3,4-tetrahydropyrazino[1,2-a]indole-3-carboxamide derivatives via intramolecular indole N-H alkylation of novel bis-amide Ugi-adducts. The main highlight of this study is the practical and highly regioselective preparation of new polycyclic functionalized pyrazino derivatives. This system is facilitated by Na2CO3 mediation in DMSO and 100 & DEG;C conditions.

Photocatalytic Aerobic Cyclization of N-Propargylamides Enabled by Selenium-p-Acid Catalysis

Yong-Hao Wang, You-Qin Jiang, Yun-Qian Zhang, Yong Ling, Liang Ming, Gong-Qing Liu

Summary: A dual catalytic approach combining photocatalyst and selenium-p-acid synergy has been used for the cyclization of N-propargylamides. This method offers a convenient access to oxazole aldehydes without using chemical oxidants, using low catalyst loadings, and utilizing air as a terminal and gratuitous oxidant. The reaction is applicable to various substrates, including aryl and alkyl propargyl amides, and can be used for the late-stage functionalization of drug molecules containing amides. Mechanistic studies indicate that the acridinium catalyst is capable of oxidizing diselenide and generating singlet oxygen (O-1(2)), which is responsible for this transformation.

Ni-catalyzed hydroalkylation of olefins with N-sulfonyl amines

Xiao-Biao Yan, Lun Li, Wen-Qiang Wu, Lun Xu, Ke Li, Yu-Cheng Liu, Hang Shi

Summary: The authors demonstrate a method to add alkanes with an amino functionality to olefins using a nickel catalyst that utilizes the amine itself as the hydride source, eliminating the need for an external hydride reagent. This approach allows for the production of valuable, complex structural motifs and chiral alpha-branched amines in organic synthesis. Additionally, the use of a P-chiral ligand further enhances the catalytic efficiency of the reaction.
