Total Synthesis of a Docosahexaenoic Acid Prostanoid Using an Intramolecular Organocatalytic Michael Reaction of a Formyl-Enal Derivative

The total synthesis of a docosahexaenoic-acid-derived prostaglandin, 4,11-diepi-4-F4t-neuroprostane, featuring a complex lateral chain was achieved for the first time. A novel prostaglandin cyclopentane skeleton obtained via an intramolecular highly selective organocatalytic Michael sequence of a formyl-enal derivative allowed the desired and exclusive thermodynamic trans configuration of the lipidic lateral chains.

A Short and Efficient Synthesis of Crocetin-dimethylester and Crocetindial

In this paper we describe an efficient six-step synthesis of crocetin-dimethylester that could be further reduced to a "four-step" synthesis through the use of in situ procedures. The simplicity of the whole process, the ready availability of starting materials, and the high overall yield render this strategy a very attractive synthesis of this very important compound, which is the key intermediate for the synthesis of several carotenoids and other polyene natural products.

A practical synthesis of the C1-C14 polyene unit 5 in ansatrienin A (mycotrien l), 1a, and other ansamycin antibiotics is described which involves elaboration of the chiral unsaturated aldehyde 6 and phosphonate 7, followed by coupling of the building blocks by Horner-Emmons-olefination and Duthaler's aldolation. The synthesis of 6 successfully applies two consecutive Evans-aldol reactions for constructing the carbon backbone.
