Rapid and efficient synthesis of 1-Arylpiperazines under microwave irradiation

, p. 6875 - 6876 (1997)
1-Arylpiperazines, finding wide applicability in pharmaceuticals were synthesized easily under microwave irradiation from bis(2-chloroethyl)amine hydrochloride and substituted anilines without any solvent. The reaction time was just 1-3 mins. 1-Arylpiperazines were synthesized in 53 to 73% yields. Potent serotonin ligands like Trifluoromethylphenylpiperazine (TFMPP) and 3-Chlorophenylpiperazine (mCPP) were also prepared in just 1 min and 2 mins respectively.

A facile Pd-catalyzed methodology providing an efficient synthetic route to biologically relevant arylpiperazines under aerobic conditions is reported. Electron donating and sterically hindered aryl chlorides were aminated to afford yields up to 97%, with examples using piperazine as solvent, illustrating an ecofriendly, cost-effective synthesis of these privileged structures.

The compound class of 1H-pyrazolo[3,4-d]pyrimidines was identified using HTS as very potent inhibitors of facilitated glucose transporter 1 (GLUT1). Extensive structure–activity relationship studies (SAR) of each ring system of the molecular framework was established revealing essential structural motives (i.e., ortho-methoxy substituted benzene, piperazine and pyrimidine). The selectivity against GLUT2 was excellent and initial in vitro and in vivo pharmacokinetic (PK) studies are encouraging.

Paragraph 196-198, (2015/12/24)
The present invention provides novel compounds described herein, such as of Formula (I), and pharmaceutically acceptable salts, solvates, hydrates, tautomers, stereoisomers, isotopically labeled derivatives, and compositions thereof. Also provided are methods and kits involving the compounds or compositions for treating or preventing proliferative diseases (e.g., cancers (e.g., leukemia, melanoma, multiple myeloma), benign neoplasms, angiogenesis, inflammatory diseases, autoinflammatory diseases, and autoimmune diseases) in a subject. Treatment of a subject with a proliferative disease using a compound or composition of the invention may inhibit the aberrant activity of cyclin-dependent kinase 7 (CDK7), and therefore, induce cellular apoptosis and/or inhibit transcription in the subject.

Sequential mono-N-arylation of piperazine nitrogens. Part 2: The role of hydrogen bonding
Eckert, Jeffrey,Chan, Tze-Ming,Osterman, Rebecca M.,Lambert, Joseph B.,Gala, Dinesh
, p. 5661 - 5665 (2007/10/03)
A mechanistic study of the simple sequential N-arylation of piperazine suggests that in an electron-withdrawing group (EWG) containing N-arylated piperazines, hydrogen bonding of the secondary amine hydrogen is important for its non-metal catalyzed conversion to N,N'-diaryl piperazines. A combination of synthetic experiments, molecular modeling, and NMR studies were carried out to test this hypothesis.
