Solvent Controlled Chemodivergent Sulfonyl Addition into Enynones: Synthesis of α-Furyl Sulfones and Stereodefined Vinyl Sulfones.

Sodium salt of aryl sulfinic acid reacts with enynone in a different manner, yielding α-furyl sulfone and stereodefined vinyl sulfone in toluene and EtOH respectively in the presence of ZnCl. The salient features of this protocol include chemoselectivity, broad substrate scope, high efficiency, high yield, and easy purification. The synthetic utilities of the products are demonstrated by cycloaddition and cis-trans photoisomerization reactions.

A Rapid, Mild and Direct Route to Sulfonimidoyl Fluoride from Sulfenamide.

We develop a rapid and mild protocol to access sulfonimidoyl fluoride-[S(VI)] from sulfenamide-[S(II)] directly. The transformation occurs via the reaction of sulfenamide with NCS (-chlorosuccinimide), water, and TBAF in acetonitrile. Water and TBAF act as the source for S═O bond formation and fluoride, respectively.

InCl catalyzed simultaneous reductive sulfoximination and -silylation: synthesis of silyloxy benzylsulfoximine.

This article describes the synthesis of -silyloxy benzylsulfoximine the reaction of salicylaldehyde and sulfoximine in the presence of silane and InCl. The steps include simultaneous reductive sulfoximination and an -silylation process. To the best of our knowledge, this is the first report of this kind of reaction, where both reductive amination (here sulfoximination) and -silylation occur concurrently.

1,2-Difunctionalization of Aryne with Sulfenamide and Organohalide: Mild and Metal-Free Access to -(-Halo)aryl Sulfilimine.

A mild and metal-free approach has been developed for 1,2-difunctionalization of aryne using sulfenamides as a nucleophile and a halogen source (CX) as an electrophile to synthesize -(-halo)aryl sulfilimines. The late-stage functionalizations of halide handles via Suzuki-Miyaura and Buchwald-Hartwig reactions exhibit the synthetic utilities of the products. The chemoselectivity, regioselectivity, rapidity, and use of economical CCl are the advantages of this protocol.

Effect of dietary tomato powder on growth performance and blood characteristics of heat-stressed broiler chickens.

This study investigated the ameliorative effect of dietary tomato powder (TP) on performance and blood characteristics of broilers under heat stress condition. A total of 240 (21 days old), unsexed Marshall broiler chicks were allotted to four dietary treatments having 6 replicates of 10 birds each in a completely randomized design (CRD). The birds were exposed to ambient temperature of 33 °C between 8:00am and 5:00 pm and relative humidity of 81.
