4-Arylcoumarins are synthesized in very good yields through solvent-free microwave irradiation of 2-hydroxybenzophenones and alkyl malonate in the presence of DBU. The one-pot synthesis is carried out with Knoevenagel co...
A general one-pot synthesis of new substituted heteroscorpionate ligands is presented. These mixed-functionality ligands were obtained in a catalyzed Peterson rearrangement starting from the substituted pyrazole, thionyl...
The series of 2-phenyl- and 2,2-diphenyl gem-dihalogenospiropentanes were employed as model compounds to study the carbenoid rearrangement with the use of methyllithium. The scope and limitations of this skeletal rearran...
Because indoline is an important intermediate of angiotensin-converting enzyme (ACE) inhibitor and the antihypertensive drug "pentopril", and also because it is a ubiquitous scaffold found in the structures of several na...
