Abstract
The efficient synthesis of fluoroalkylated pyrazolo[1,5-c]quinazolines by reactions of 3-diazoindolin-2-ones with methyl β-fluoroalkylpropionates has been achieved. This protocol affords two regioisomers of fluoroalkylated pyrazolo[1,5-c]quinazolines with excellent yields in total. The dipolarophilicity of methyl β-fluoroalkylpropionates enhanced by perfluoroalkyl groups is crucial for the high efficiency of this [3 + 2] cycloaddition reaction.

Abstract
An efficient, metal-free approach to access pyrazolo-[1,5-c]quinazolines with 3-ylideneoxindoles and tosyldiazomethane (TsDAM) under mild aqueous reaction conditions has been developed and the solvent involvement in the present reaction has also been explored for the first time. This greener approach involves 1,3-dipolar cycloaddition, regioselective ring expansion, followed by the elimination of tosyl group with aqueous base in a single operation, and the product can be isolated in high purity without column chromatographic separation. The method is also compatible with a large variety of functional groups, providing good to excellent yields in water, thus resulting in a decrease of environmental impact in the pharmaceutical industry.

Abstract
Background:
This paper reviews the research progress of pyrazoloquinazolines which
widely used in the field of medicine and pesticide in recent years. Five types of
pyrazoloquinazolines are introduced: pyrazolo [4,3-h]quinazolines, pyrazolo[1,5-c]quinazolines,
pyrazolo[4,3-f]quinazolines, pyrazolo[1,5-a] quinazolines , pyrazolo[1,5-b]quinazolines, and their
new progress in the synthesis methods and treatment of diseases.
Methodology:
The derivatives of pyrazoloquinazolines exhibit a wide range of pharmacological
properties such as antibacterial, anticancer, antioxidants, anti-inflammatory, anti-diabetic, antiviral
activities. Consequently, their syntheses have attracted significant interest. Various methodologies
have been developed for the synthesis and functionalization of these class of compounds.
Conclusion:
In the present article, the relevant and recent advances in the field will be briefly
covered.
