Ionic Effects on the Stereoselectivities of Diels−Alder Reactions: The Cyclopentadiene−Methyl Acrylate Reaction in Aqueous LiCl, NaCl, NaBr, CaCl2, LiClO4, and Guanidinium Chloride
TL;DR: In this paper, the variations in the endo-and exo-stereoselectivities for the reaction of cyclopentadiene (CP) with methyl acrylate (MA) have been investigated in salt−solvent reaction media (SSRM) at different concentrations of salts.

Self-assembly with degenerate prototropy.
TL;DR: The utility of degenerate prototropy is demonstrated herein by developing heterocycle-based AADD-type self-assembling modules that exist as "single set of protameric pair (duplex)" in both solution and solid states.

Synthesis and RNA Binding Selectivity of Oligonucleotides Modified with Five-Atom Thioacetamido Nucleic Acid Backbone Structures
TL;DR: The UV-Tm experiments for binding affinities of these mixed backbone ONs with complementary DNA and RNA sequences revealed important results such as significantly higher RNA-binding selectivity as compared with complementaryDNA.

Efficacy of 4-methyl-7-hydroxy coumarin derivatives against vectors Aedes aegypti and Culex quinquefasciatus
Madhavi Deshmukh,Pushpa Pawar,Mary Joseph,Usha D. Phalgune,R. V. Kashalkar,Nirmala R. Deshpande +5 more
TL;DR: 3,6,8-tribromo-7-hydroxy-4-methyl-chromen-2-one was found to be the most potent against IVth instar larvae of C. aegypti and hatched larvae showed 100% mortality in the successive instars.

Mukund K. Gurjar,Seetaram Mohapatra,Usha D. Phalgune,Vedavati G. Puranik,Debendra K. Mohapatra +4 more
TL;DR: In this article, an enantioselective synthesis of the C12-C29 fragment of amphidinolide E is described, which includes an intramolecular mercuriocyclization reaction, stereoselectively introduction of methyl group at the C2 position, and Stille coupling for the introduction of the diene side chain.
