Mild TiIII- and Mn/ZrIV-catalytic reductive coupling of allylic halides: Efficient synthesis of symmetric terpenes

(Chemical Equation Presented) Two new efficient methods for the regioselective homocoupling of allylic halides using either catalytic Ti III or the combination Mn/ZrIV catalyst have been developed. The regio- and stereoselectivity of the process proved to increase significantly when the Mn/ZrIV catalyst is used as the coupling reagent and when cyclic substituted allylic halides are used as substrates. The use of Lewis acids such as collidine hydrochloride allowed the quantity of catalyst to be lowered up to 0.05 equiv. We have proved the utility of these protocols with the synthesis of different terpenoids such as (+)-β-onoceradiene (1), (+)-β-onocerine (2), squalene (5), and advanced key-intermediates in the syntheses of (+)-cymbodiacetal (3) and dimeric ent-kauranoids as xindongnin M (4a).

On the Regioselectivity of Coupling of Substituted Allyl Radicals. Steric Versus FMO Control

The photo-induced decomposition of substituted-homoallylic 4-nitrobenzenesulfenates produces substituted allyl radicals which undergo dimerization and coupling with the 4-nitrobenzenethiyl radical.The regioselectivity of the dimerization of the allyl redi

SPECIFIC ALLYLIC-ALLYLIC COUPLING PROCEDURES EFFECTED BY LIGAND-INDUCED ELIMINATION FROM DI(ALLYLIC)PALLADIUM SPECIES

Bis(allylic)palladium complexes can be induced to undergo reductive elimination by replacement of phosphine ligands in the system with ?-acidic ligands.The product 1,5-dienes, formed in high yield, are predominantly the 'head-to-head' coupled isomers.The bis(allylic)palladium intermediates may be formed by addition of an allylic Grignard or trialkyl(allylic)tin reagent to an(η3-allyl)palladium chloride complex, or by 1,3-diene condensation.The latter process leads to cyclodimerization, 'unusual' for palladium catalysed reactions.
