In the current paper, we successfully developed and
used metal−organic frameworks (MOFs) based on MIL-101(Cr)-NH2
with phosphorus acid functional groups MIL-101(Cr)-N(CH2PO3H2)2
. The synthesized metal−organic frameworks
(MOFs) as a multi-functional heterogeneous and nanoporous
catalyst were used for the synthesis of N-amino-2-pyridone and
pyrano [2,3-c]pyrazole derivatives via reaction of ethyl cyanoacetate or ethyl acetoacetate, hydrazine hydrate, malononitrile, and
various aldehydes. Thefinal step of the reaction mechanism was
preceded by a cooperative vinylogous anomeric-based oxidation.
Recycle and reusability of the described catalyst MIL-101(Cr)-N(CH2PO3H2
)
2
were also investigated.
