General description
Layer-by-layer assembly of 4-aminothiophenol and ytterbium(III)trifluoromethanesulfonate hydrate film has been investigated by atomic force microscopy (AFM). Bis(oxazolinyl)-pyridine-scandium(III) triflate complexes have been reported to catalyze the enantioselective Friedel-Crafts addition of various indoles.
Application
Ytterbium(III) trifluoromethanesulfonate hydrate (Yb(OTf)3) was employed as Lewis acid catalyst for the following studies:
- Synthesis of the dihydropyrimidine (DHPM) derivative monastrol, by Biginelli cyclocondensation.
- Cross-aldol reaction between ketone and aldehyde.
- Synthesis of β-keto enol ethers.
- Synthesis of deoxypenostatin A in a novel, stereoselective intramolecular Diels-Alder reaction.
