Ethyl oxamate reacted with anthranilic acid derivatives at the amide or the ester group leading to the formation of respective esters or amides. A simple method was developed for preparation of alkyl 3-amino-4-oxo-3,4- dihydroquinazoline-2-carboxylates. Nauka/Interperiodica 2007.

Imidazolium chloride as an additive for synthesis of 4(3H)-quinazolinones using anthranilamides and DMF derivatives

Imidazolium chloride as an environmentally benign additive efficiently facilitates construction of 4(3H)-quinazolinones using anthranilamides and DMF derivatives. A series of 4(3H)-quinazolinones were prepared in moderate to excellent yields without conventional oxidants, metal catalysts and corrosive acids or other additives.

Synthesis of N-(4-oxo-3,4-dihydroquinazolin-3-yl)succinimide and N-(4-oxoquinazolin-3-yl)succinamic acid derivatives based thereon

The reaction of anthranilic acid hydrazide with diethyl oxalate under microwave irradiation was accompanied by decarboxylation with formation of 3-amino-3,4-dihydroquinazolin-4-one, and acylation of the latter with succinic anhydride gave N-(4-oxo-3,4-dihydroquinazolin-3-yl)siccinimide which was converted into various N-(4-oxo-3,4-dihydroquinazolin-3-yl)succinamic acid derivatives.
