The importance of tandem reactions is evident--besides their pragmatic value, they have an
aesthetic appeal. The author presents a survey of these reactions that will rivet the attention …

The development of oxochromium (VI)‐amine reagents as oxidants in organic synthesis has
evolved since the early studies of Sisler which described the use of adducts of heterocyclic …

Publisher Summary The Amaryllidaceae alkaloids constitute an important group of naturally
occurring bases possessing a diversity of functionality and structure. The chapter explores …

Abstract The Diels–Alder reaction is one of the most useful reactions available to the
synthetic organic chemist. It is thus surprising that the intramolecular version, in which both …

A series of 3-(alkyl and aryl) methylene-2, 3-dihydro-1H-isoindol-1-one derivatives was
synthesized by a one-pot reaction sequence involving lithiation of 2-(or 3-) halogeno-N …

The total synthesis of several members of the hydroxylated phenanthridone subclass of the
Amaryllidaceae alkaloid family has been carried out.(±)-Lycoricidine and (±)-7 …

A convergent synthesis of a protected version of (+)-lycoricidine has been accomplished in
13 steps from L-arabinose. Preparation of the aminocyclitol moiety 50 employed a novel …

Concise synthetic routes from cyclopentadiene 4 to the lycoricidine and pancratistatin
analogues 13, 14 and 17 have been developed. The key step involved the silver isocyanate …

A highly diastereoselective route to unsaturated amino alcohol derivatives has been
developed that features the [4+ 2] cycloaddition of chiral acyl nitroso compounds to a variety …

Some “seco” analogues of Amaryllidaceae alkaloids narciclasine and lycoricidine have
been prepared in enantiomerically pure form from D-glucose using Ferrier carbocyclization …
