Abstract
Sulfenic acids react as both nucleophiles and electrophiles, which may be attributable to interconversion between sulfenyl and sulfinyl tautomers. We demonstrate one-pot trapping of both tautomeric forms of glutathione sulfenic acid by LCMS. The sulfinyl tautomers are characterized by reaction with nucleophilic reagents such as dimedone and cyanide, giving unique products that are analogous to corresponding adducts of aldehydes. Likewise, we show that aldehyde reactive reagents such as silyl enol ethers also react with glutathione sulfenic acid to give products characteristic of both sulfenyl and sulfinyl tautomers.

Abstract
A transition-metal-free process for the synthesis of 1,4-dihydroquinoline derivatives starting from simple enaminones with aldehydes via intermolecular cascade cyclization in a one-pot protocol is developed. This methodology affords a variety of products in moderate to good yields. Particularly, the use of the enaminone fragment in 1,4-dihydroquinoline derivatives 3 as a leaving group for further diverse applications with C-nucleophiles is proved to be feasible.

Abstract
2-Methylindole was used as an indicative nucleophile for rapid screening of MCRs of aldehydes with two different nucleophiles. By removal of some samples that have characteristic color associated with the generation of di(indolyl)methane derivatives the difficulties encountered in the product analysis were alleviated significantly.

Abstract
An ecofriendly, one-pot, three component ZnO nanoparticles-mediated synthesis of 4H-chromene in water under thermal condition has been described. The highly product-selective three component electrophilic reaction of 2-hydroxybenzaldehyde with an active methylene compound and another carbon-based varied nature of nucleophile has been developed by a reversible alkylation procedure using greener "NOSE" approach. Greenness of the process was well instituted, as water was used both as reaction media as well as medium for the synthesis of catalyst. In these reactions, the use of nano-ZnO as a catalyst was documented to be crucial for rendering the reactions possible in water media, while replacing nano-ZnO with other acids or bases resulted in the generation of too many side products. The catalyst can be efficiently recycled up to the sixth run, an essential point in the area of green chemistry. The methodology provides cleaner conversion, shorter reaction times, and high selectivity, which make the protocol globally putative. The crystal structures of 4H-chromene, easily produced by a chromatography-free highly product-selective reaction, were explored by means of single crystal X-ray diffraction analysis, and H-bonding arrangements of one signified compound prepared is presented. In optimized mild conditions, the isolated yields are 86-93%.
