Wanna know what happens if you consider MOFs and HBC together? Take a look to this highlight, just published in CrystEngComm
The highlight entitled “Metal-organic frameworks (MOFs) bring new life to hydrogen-bonding organocatalysts in confined spaces” has just been published at CrystEngComm. In this work, together with Prof. David Díaz (Universität Regensburg), we have compiled and studied the literature which involves the intriguing idea of … Continue reading
HOCA to publish a New Synthesis of Chiral 2-Oxospiro-[indole-3,4′- (1′,4′-dihydropyridines)]
We are interested in the enantioselective synthesis of highly functionalized molecules with biological activity. In this frame, we have just published “a preliminary study” in the development of a “New Organocatalytic Asymmetric Synthesis of Highly Substituted Chiral 2-Oxo Spiro-[indole-3,4′- (1′,4′-dihydropyridine)] … Continue reading
