Synthesis of labile all-trans-7,8,7′,8′-bis-acetylenic carotenoids by bi-directional Horner-Wadsworth-Emmons condensation

A new stereoselective synthesis of the C40-bis-acetylenic carotenoids all-trans-(3R,3′R)-alloxanthin and all-trans-3,4,7,8,3′,4′,7′,8′-octadehydro-β,β-carotene, both compounds featuring a stereochemically labile C7-C10 enyne, based on a bi-directional Horner-Wadsworth-Emmons (HWE) reaction of a C15-phosphonate and a central C10-dialdehyde, is reported. The triene unit of the latter fragment was synthesized using the acyclic metathesis/dimerization reaction.

Stereoselective total synthesis of the acetylenic carotenoids alloxanthin and triophaxanthin

Stereoselective total synthesis of the C40-diacetylenic carotenoid alloxanthin (1) and the C31-acetylenic apocarotenoid triophaxanthin (2) was accomplished by Wittig condensation of C 10-dialdehyde 20 or C16-ket

Stereocontrolled synthesis of optically active β-D-glucopyranosides of 3-hydroxy-7,8-didehydro-β-ionol

A stereocontrolled synthesis of optically active β-D-glucopyranosides 1-4 of 3-hydroxy-7,8-didehydro-β-ionol utilizing an asymmetric transfer hydrogenation to α,β-acetylenic ketones catalyzed by chiral ruthenium complexes as the key step is described.
