MCM-41@Schiff base-Co(OAc)2 as an efficient catalyst for the synthesis of pyran derivatives

Heterogeneous ordered mesoporous silica materials catalyst, MCM-41@Schiff base-Co(AcO)2, reveals high catalytic performance within the synthesis of pyran derivatives using the multicomponent reaction of aldehydes, malononitrile and 2-naphthol (

Nano polypropylenimine dendrimer (DAB-PPI-G1): As a novel nano basic-polymer catalyst for one-pot synthesis of 2-amino-2-chromene derivatives

The nano polypropylenimine dendrimer (DAB-PPI-G1) Lewis base catalyst was found to be a highly efficient and recoverable catalyst for the rapid and convenient synthesis of 2-amino-2-chromene derivatives through the three-component condensation of aromatic aldehydes, malononitrile or ethyl cyanoacetate and phenols under solvent-free conditions in excellent yields and short reaction times.

Diversity oriented synthesis of benzoxanthene and benzochromene libraries via one-pot, three-component reactions and their anti-proliferative activity

Libraries of benzoxanthenes, as well as of benzochromenes, were efficiently synthesized via one-pot, three-component reactions of 2-naphthol, aldehydes, and cyclic 1,3-diketones/malononitrile/ethyl cyanoacetate in the presence of catalytic amount of eerie
