5-Carbonyl-1,3-oxazine-2,4-diones from N-Cyanosulfoximines and Meldrum’s Acid Derivatives

2020

At elevated temperatures, N-cyanosulfoximines react with Meldrum's acid derivatives to give sulfoximines with N-bound 5-carbonyl-1,3-oxazine-2,4-dione groups. A representative product was characterized by single-crystal X-ray structure analysis. The product formation involves an unexpected molecular reorientation requiring several sequential bond-forming and -cleaving processes.

Synthesis of V-ZrSiO4 solid solutions

1990

This letter describes the results of the preparation of V-ZrSiO 4 solid solutions from a sol or alkoxide and solute salts. This technique allows a greater degree of product formation to be achieved at lower temperatures, as well as the possibility of studying the characteristics of possible solid solutions

Modeling of growth and lactate fermentation by Lactococcus lactis subsp. lactis biovar. diacetylactis in batch culture

1993

The kinetic behaviour of Lactococcus lactis subsp. lactis biovar. diacetylactis was studied in batch culture under non-limiting conditions that allow high growth and product formation. A model based on laboratory results is proposed for growth and l-lactate fermentation. It shows the necessity for differentiating biomass into three physiological states, two active, Xg (growth + acidification) and Xng (acidification), and one inactive, Xi. The kinetic theory of the model demonstrates the non-competitive nature of fermentation end-product inhibition on growth and acidification, and describes the passage from one physiological state to another. Satisfying simulations were obtained for batch fe…
