In conclusion, this paper describes a convenient and efficient process for the synthesis of β-acetamido ketones through the condensation of an aryl aldehyde, an acetophenone, acetyl chloride, and acetonitrile in the presence of boric acid as a solid heterogeneous catalyst at room temperature
Betamethasone dipropionate is a steroid ester that is betamethasone in which the hydroxy hydrogens at positions 17 and 21 are replaced by propanoyl groups
It is widely used to treat asthma, allergic rhinitis, and dermatoses
The 16α-methyl was introduced stereoselectively with Divergent Chemo- and Biocatalytic Route to 16β-Methylcorticoids: Asymmetric Synthesis of Betamethasone Dipropionate, Clobetasol Propionate, and Beclomethasone Dipropionate Betamethasone release as well as the in vitro cytocompatibility with chondrocytes and fibroblast cells were also evaluated
Among the ratio of mobile phase that had identified, (90:
Dexchlorpheniramine, usually used in form of maleate salt, is the pharmacologically active dextrorotatory enantiomer of chlorpheniramine [], an

It stimulates the synthesis and release of surfactant (2), which lubricates the lungs, allowing the air sacs to slide against one another without sticking when the infant breathes
