A one-pot method for the synthesis of the title compounds is also presented [reaction of (V)].

A novel approach to construct diverse enantioenriched tricyclic heterocycles is developed using a hitherto not described asymmetric, organocatalytic allylic substitution/Diels—Alder cascade sequence.

This new title reaction provides an easy and facile access to a wide range of different functionalized quinoline and isoquinoline derivatives from readily available starting materials under mild conditions.

Over the past decade, lanthanide compounds have become of increasing interest in the field of Single Molecule Magnets (SMMs) due to the large inherent anisotropy of the metal ions. Heavy lanthanide metal systems, in particular those containing the dysprosium(III) ion, have been extensively employed to direct the formation of a series of SMMs. Although remarkable progress is being made regarding the synthesis and characterization of lanthanide-based SMMs, the understanding and control of the relaxation dynamics of strongly anisotropic systems represents a formidable challenge, since the dynamic behaviour of lanthanide-based SMMs is significantly more complex than that of transition metal systems. This perspective paper describes illustrative examples of pure dysprosium(III)-based SMMs, published during the past three years, showing new and fascinating phenomena in terms of magnetic relaxation, aiming at shedding light on the features relevant to modulating relaxation dynamics of polynuclear lanthanide SMMs.
