auxiliary
(adjective)
Helping; giving assistance or support.
Examples of auxiliary in the following topics:
-
Enantioselective Aldol Reactions
- A substituent serving this purpose is commonly called a chiral auxiliary.
- Chiral auxiliaries have been prepared from different kinds of natural products, including amino acids, alkaloids and terpenes.
- In this section of the text we shall make use of a family of oxazolidinone auxiliaries prepared by the Evans group (Harvard).
- Three examples of these auxiliaries are shown in the following diagram.
- If the auxiliary remains chelated to the enolate during the aldol reaction the stereochemical outcome is changed.
-
Black and White Abolitionism
- Abolitionists included those who joined the American Anti-Slavery Society or its auxiliary groups in the 1830s and 1840s.
- Abolitionists included those who joined the American Anti-Slavery Society or its auxiliary groups in the 1830s and 1840s as the movement fragmented.
-
Total Synthesis
- This is usually a chiral auxiliary, which can block one face of a stereocenter, forcing the reaction to occur only from the other side.
- The addition of a chiral auxiliary that can easily be removed exploits the chemically different properties from one diastereomer to another, which is the foundation of diastereoselectivity.

Hispanics in WWII
- With the creation of the Women's Army Auxiliary Corps (WAAC), predecessor of the Women's Army Corps (WAC), and the U.S.
- After their basic training at Fort Oglethorpe, Georgia, the Puerto Rican WAC unit, Company 6, 2nd Battalion, 21st Regiment of the Women's Army Auxiliary Corps, a segregated Hispanic unit, was assigned to the Port of Embarkation of New York City to work in military offices that planned the shipment of troops around the world.
- Serving overseas was dangerous for women; if captured, WAACs, as "auxiliaries" serving with the Army rather than in it, did not have the same protections under international law as male soldiers.
-
Carbon-Carbon Bond Formation
- This acid is attached to a chiral auxiliary before undergoing a selective aldol reaction with the chiral aldehyde shown at the bottom right.
-
Aging and the Respiratory System
- Auxiliary intercostal muscles stiffen and shape the rib cage.
-
Homefront Security
- La Guardia also formalized the creation of Civil Air Patrol (CAP) - the civilian auxiliary of the United States Air Force - with Administrative Order 9, signed on 1 December 1941 and published 8 December 1941.
- Under the CAP and its Coast Guard counterpart, the Coast Guard Auxiliary, civilians were trained to spot air raids, participate in search-and-rescue missions, and help with transportation.

- (Some auxiliary modules may contain a single phrase.)
- "Rock songs almost always end with material that has been heard earlier in the song: either a core module, a core-based auxiliary module, or a reprise of the introduction" (Summach, p. 47).Outros exhibit closing rhetoric (see below).
- Auxiliary modules may also be present (I, O, J, or X).
