Heterocyclic compounds are well known for their different biological activity. The heterocyclic analogs are the building blocks for synthesis of the pharmaceutical active compounds in the organic chemistry. These derivatives show various type of biological activity like anticancer, antiinflammatory, anti-microbial, anti-convulsant, anti-malarial, anti-hypertensive, etc. From the last decade research showed that the quinoline analogs plays a vital role in the development of newer medicinal active compounds for treating various type of disease. Quinoline reported for their antiviral, anticancer, anti-microbial and anti-inflammatory activity. This review will summarize the various synthetic approaches for synthesis of quinoline derivatives and to check their biological activity. Derivatives of quinoline moiety plays very important role in the development of various types of newer drugs and it can be used as lead compounds for future investigation in the field of drug discovery process.

1,3-Enynes are important building blocks in organic synthesis and also constitute the key motif in various bioactive natural products and functional materials. However, synthetic approaches to stereodefined substituted 1,3-enynes remain a challenge, as they are limited to Wittig and cross-coupling reactions. Herein, stereodefined 1,3-enynes, including tetrasubstituted ones, were straightforwardly synthesized from cis or trans-alkynylated oxiranes in good to excellent yields by a one-pot cascade process. The procedure relies on oxirane deprotonation, borylation and a stereospecific rearrangement of the so-formed alkynyloxiranyl borates. This stereospecific process overall transfers the cis or trans-stereochemistry of the starting alkynyloxiranes to the resulting 1,3-enynes.

The U.S. Food and Drug Administration approved 18 new drugs that incorporate the cyclopropyl structural motif in the time frame from 2012 to 2018. This review provides an overview of synthetic approaches to these drugs with emphasis on the construction of the cyclopropyl moiety or its incorporation into the key building blocks for assembly of the highlighted drugs. Based on the structural diversity of these drugs, synthetic approaches for the construction and introduction of the cyclopropyl moiety into their structure are diverse and include: cycloalkylation (double alkylation) of CH-acids, catalytic cyclopropanation of alkenes with diazo compounds, the Simmons–Smith reaction, the Corey–Chaykovsky reaction, the Kulinkovich reaction, the Horner–Wadsworth–Emmons reaction, and cycloaddition. In addition, the cyclopropyl structure was also introduced into the drug substance intermediates via simple cyclopropyl-moiety-containing building blocks, such as cyclopropylamine, cyclopropanesulfonamide, cyclopropanecarbonyl chloride, and cyclopropylmagnesium bromide.1 Introduction2 Synthesis of Recently Approved Cyclopropyl-Moiety-Containing Drugs2.1 Cabozantinib2.2 Trametinib2.3 Simeprevir2.4 Ledipasvir2.5 Olaparib2.6 Tasimelteon2.7 Finafloxacin2.8 Paritaprevir2.9 Lenvatinib2.10 Lumacaftor2.11 Lesinurad2.12 Grazoprevir2.13 Glecaprevir2.14 Ozenoxacin2.15 Voxilaprevir2.16 Naldemedine2.17 Tezacaftor2.18 Tecovirimat3 Conclusion
