Highly efficient silylcyanation of ketones by a catalytic double activation method using lewis acid and N-oxide catalysts

, 2003
An efficient protocol for addition of TMSCN to ketones by employing 3 mol% achiral Schiff base-Ti(IV) complex as the Lewis acid and 3 mol% N-oxide as the Lewis base in a manner of double activation was described.

Cardiopulmonary responses to acute exogenous ketosis at rest, and during submaximal and maximal exercise

Physiological Reports
Nutritional ketosis achieved through various methods in animals and humans has been shown to augment cardiac efficiency and function. However, this response during exercise has not been well characterized.
