Approaches to selective isoprenologation via reactions of (η3-allyl)Fe(CO)4+ with allyl nucleophiles

The reactions of substituted (η3-allyl)Fe(CO)4BF4 complexes 1 with various allyl-metals and dienolate derivatives have been investigated in search of a method for regio- and stereocontrolled allyl-allyl coupling.All three classes of allyl derivatives react with 1 in moderate to good yield with variable regioselectivity; the silyl derivatives 2 generally provide good regioselectivity for attack at the less substituted terminus of unsymmetrical derivatives of 1 but deprotonation of the 1,1-dimethylallyl complex 1e prevents efficient isoprenylation.Although deprotonation of 1e also dominates with the siloxydienes, the lithium dienolates couple efficiently with 1; however, reaction at the α position of the dienolate dominates.

Carbon-Carbon Bond Formation at the γ-Position of Dienolates via the Germanium Masked Dienolates

Trapping of the lithium dienolate (1), derived from 3-methyl-2-butenoate, with Me3GeX (X = Br or Cl gives the α-germylated derivative (2), which reacts with various electrophiles at the γ-position.

ALDOL REACTIONS, CONJUGATE ADDITIONS, AND ALKYLATION REACTIONS OF O-SILYLATED KETENE ACETALS UNDER NEUTRAL CONDITIONS

Aldol reactions, conjugate additions, and alkylation reactions of O-silylated ketene acetals take place under neutral conditions by using a high pressure technique.

Regioselective Head-to-tail Coupling of Allylic Trialkylstannanes with Allylic Halides under High Pressure

Allylic trialkylstannanes (1) regioselectively react with allylic halides (2) at room temperature under high pressure (10 kbar) to give head-to-tail coupling products (3) in high yields.
