Kandeel, "Reactions with heterocyclic
amidines. VIII.
These
amidines are electrically neutral in undisturbed water, but when carbon dioxide bubbles through, the compounds transform into amidinium bicarbonate salts that act as surfactants.
The cyano compound 4 was converted to
amidine according to a standard procedure [7].
(1998) Drugs and the Law in New Zealand,
Amidine Publications, Dunedin.
Gupta, Synthesis and anti-inflammatory activity evaluation of some sulfonamide and
amidine derivatives of 4-aryl-3-(2 or 4-picolyl)-2-imino- 4-thiazolines, Indian J.
The initiator, 2,2'-azobis (2-metilpropion
amidine) dihydrochloride (V50, Aldrich) was used as received.
Current developments in resistance to
amidine and pyrethroid tickicides in Australia.
At these pH values, the nucleophilic attack of an R-N[H.sub.2] on one of the two outer backbone carbon atoms of dimethyl pimelimidate produces a tetrahedral intermediate that splits into the
amidine link and methanol.
Radicals of this type can be prepared by reduction of the corresponding cations, which can be made by a variety of routes, the most versatile of which involves the condensation of a per-silylated
amidine with S|Cl.sub.2~ or Se|Cl.sub.2~.
Subsequent addition of benzyl amine, which rapidly cyclized via a transient
amidine salt (3), led to 2,3-disubstituted 3H-quinazolin-4-ones (4) (Scheme-6).
Cyclic
amidine bases such as DBU also support rapid and efficient BUR cures.
It has been known for some time that
amidine and guanidine derivatives will inhibit C-mediated hemolysis (i.e., C activation) (27).
