Others pivot from both bottom (like a hopper) and the side (like a casement). Also called Dual Action. Double-Hung Windows: Include offset upper and lower sashes, which can both move up and down in the frame. A window having two vertically sliding sash, each closing a different part of the window.
Reaction of sugar oxazolines with primary amines. In order to scrutinize the reaction pathway and structure of the reaction product, we started with a simple sugar oxazoline and a primary amine, carrying no other functional groups.
these methods involve reaction of an amine with an activated carbonyl compound (i.e. acid. chloride), very similar to the method used to prepare esters: The amide is an important functional group present in a number of types of drugs. molecules (local anesthetics, antiarrhythmics, etc). It is also the key linking moiety. in proteins and peptide drug products: II.
