ing an operational semantics to finite automata Nadezhda Baklanova, Wilmer Ricciotti, Jan-Georg Smaus, Martin Strecker IRIT (Institut de Recherche en Informatique de Toulouse) Université de Toulouse, France firstname.lastname @irit.fr ?,?? Abstract. There is an apparent similarity between the descriptions of small-step operational semantics of imperative programs and the semantics of finite aut...

The reactivity of a trisubstituted alkene surfactant (8-methylnon-7-ene-1 sulfonate, 1) to airborne singlet oxygen in a solution containing E. coli was examined. Surfactant 1 was prepared by a Strecker-type reaction of 9-bromo-2-methylnon-2-ene with sodium sulfite. Submicellar concentrations of 1 were used that reacted with singlet oxygen by an "ene" reaction to yield two hydroperoxides (7-hydr...

The concept of multicomponent reactions (MCR) [1] has been around in organic chemistry since the very early days. Indeed, the first example known in literature, the Strecker synthesis of α-aminonitriles [2], has been developed into an industrial process for the production of methionine in an annual scale of several hundreds of thousand tons per year. In addition, a lot of syntheses of heterocyc...

Honey volatiles exhibit a potential role in distinguishing honeys as a function of botanical origin, but heating of honey generates artefacts such as compounds of Strecker degradation and Maillard reaction products. This short review is focused on the most recently applied methods for honey volatiles fingerprinting (without generation of thermal artefacts): headspace extraction (dynamic headspa...

I. Halogen atoms have been introduced on the Ê-carbons of amino acids in order to dissociate effects on pKa of the amino group on transport, from effects of the hydrophilic or hydrophobic character of the side chain. 2. ~-Monofluoromethyland a-trifluoromethylalanine have been synthesized by adaptations of the Strecker synthesis. The pKa of the amino group in these 2 cases was lowered by x.6 and...

Nutty flavor in Cheddar cheese is desirable, and recent research demonstrated that 2- and 3-methyl butanal and 2-methyl propanal were primary sources of nutty flavors in Cheddar. Because malty strains of Lac-tococcus lactis (formerly Streptococcus lactis var. malti-genes) are characterized by the efficient production of these and other Strecker aldehydes during growth, this study investigated t...
