Ethyl carbamate and a series of related compounds were given in single intraperitoneal doses to pregnant Syrian hamsters on Day 8 of gestation, and fetuses were examined for malformations on Day 13 of gestation. Urethan produced a variety of malforma tions and growth retardation. Of the compounds modified in the carboethoxy end, n-propyl carbamate was as teratogenic as the ethyl carbamate, and ...

This study describes, for the first time, in situ generation of indium organometallic reagents environmentally friendly deep eutectic solvents (DESs). The allylation process different carbonyl compounds is achieved mediated by metal and using cheap allyl chloride derivatives. unique DES properties allow to perform reaction at room temperature under air, obtaining yields ranging from 45% 99%. It...

MINDO-force calculations have been performed on phenyl and cyclopropyl substituted allyl cations and anions with complete energy minimization. It is found that the phenyl ring destabilizes the allyl cations when substituted at the terminal and at the center carbon atom of the cation, while the cyclopropyl ring stabilizes the allyl cation when substituted at the terminal carbon atoms, but destab...

The photodissociation of allyl-d2 iodide (H2C5CDCH2I) and the dynamics of the nascent allyl-d2 radical (H2CCDCH2) were studied using photofragment translational spectroscopy. A previous study found the allyl radical stable at internal energies up to 15 kcal/mol higher than the 60 kcal/mol barrier to allene1H formation as the result of a centrifugal barrier. The deuterated allyl radical should t...

Small amounts of exogenous lipopolysaccharide (LPS) (10 ng/kg-100 microg/kg) enhance the hepatotoxicity of allyl alcohol in male Sprague-Dawley rats. This augmentation of allyl alcohol hepatotoxicity appears to be linked to Kupffer cell function, but the mechanism of Kupffer cell involvement is unknown. Since Kupffer cells produce tumor necrosis factor-alpha (TNF alpha) upon exposure to LPS, an...

It is important to prevent and improve diabetes mellitus and its complications in a safe and low-cost manner. S-Allyl cysteine, an aged garlic extract with antioxidant activity, was investigated to determine whether S-allyl cysteine can improve type 2 diabetes in Otsuka Long-Evans Tokushima Fatty rats with nonalcoholic fatty liver disease. Male Otsuka Long-Evans Tokushima Fatty rats and age-mat...

Herein is reported the first example of palladium-catalyzed asymmetric allylic alkylation (AAA) reactions involving 2-aza-π-allyl palladium intermediates. The 2-aza-π-allyl complex was generated via a novel mode of activation of N-allyl imines. Pd-catalyzed C(sp3)-H activation of N-allyl imines and subsequent nucleophilic attack by glycinates delivered vicinal diamino derivatives as the sole re...
