REGIOCONTROLLED 1,2-, 1,4-, AND 1,6-ADDITIONS OF ORGANOMETALLICS TO UNSATURATED THIOAMIDES

1,4-Addition of allyllithiums to α,β-unsaturated thioamides and 1,4-(kinetic) and 1,6-(thermodynamic)regiocontrolled additions of lithium enolates to thiosorbamide are reported.

ALLYL ALKALI METAL COMPOUNDS

Physical measurements, primarily high resolution nuclear magnetic resonance, support the contention that the allyl alkali metal compounds are ionic in solution but exist as intimate ion pairs or clusters.The sodium, potassium, rubidium and cesium compounds, when first formed at low temperatures, are in a more freely rotating form.

The allyl group exchange reaction between tri( substituted allyl) stannyllithium and ( substituted allyl) lithium

Triallylmethylstannane, diallylmethallylmethylstannane, allyldimethallylmethylstannane, and trimethallylmethylstannane were produced by the reaction of triallylstannyllithium with methallyllithium followed by treatment with iodomethane. The formation of similar mixture of such stannanes was also observed when trimethallylstannyllithium was treated with allyllithium and iodomethane successively. These results indicate that the reaction of tri(substituted allyl)stannyllithium with (substituted allyl)lithium forms the equilibrium mixture of tri(substituted allyl)stannyllithiums having all the possible combinations of substituents.

Diastereoselective synthesis of 3,3-disubstituted oxindoles from atropisomeric N-aryl oxindole derivatives

Diastereoselective synthesis of 3,3-disubstituted oxindoles has been examined by transformations involving nucleophilic addition, alkylation, and cycloaddition using chiral racemic N-aryl oxindoles bearing C-N axial chirality. The most striking features of this approach are high diastereoselectivities (up to >95:5) when using ortho-monosubstituted N-aryl oxindoles and easy removal of the p-(benzyloxy)aryl moiety in the axially twisted amides by a mild two-step sequence.

First asymmetric synthesis of boehmeriasin A

The first asymmetric synthesis of phenanthroquinolizidine alkaloid (R)-boehmeriasin A is described. Two alternative synthetic pathways to the key intermediate (RS,R)-4 were achieved through a combination of highly diastereoselective 1,2-nucleophilic addition on (-)-(S)-l-amino-2-(methoxy methyl)pyrrolidine hydrazones with a ring-closing metathesis to ensure the construction of the piperidine template. A subsequent acylation/oxidation/aldol condensation/radical cyclization sequence completed the assembly of the title (R)configured natural product.

The preparation of pure allyl- and benzyl-type organoalkali intermediates via organotin compounds

Superbase metalation of alkenes or alkylbenzenes and subsequent condensation with trialkylstannyl chloride affords allyl- or benzyl-type organotin compounds that can be isolated in pure form.Treatment with soluble reagents such as methyllithium, trimethylsilylmethylpotassium and trimethylsilylmethylcaesium generates the corresponding organoalkali derivatives almost quantitatively and in high purity, suitable for kinetic or spectroscopic studies.

β-Substituted Organoalkaline Tri- and Tetra-anions; Preparation, Stability, and Reactivity

New β,γ-, β,β'-disubstituted organometallic trianions of the type C(Y)C(Y')C(8) and C(Y)CC(Y') (18) (Y = or (*) Y' = O, PhN), β-substituted organodimetallic trianions of the type CC(PhN)C (25) with alkali-metal cations (Li, Na, and K), and a lithiated tetra-anion of the type CC(PhN)C(PhN)C (32) are obtained from the corresponding substituted organomercury(II) compounds via low-temperature mercury-alkali metal transmetallation.The starting organomercurials can be obtained by solvomercuriation from suitable unsaturated systems.These polyanion derivatives are stable species only at temperatures in the range -78 to -100 deg C; at higher temperatures rapid decomposition takes place via either a β-elimination process or proton abstraction from the reaction media.The new polyanionic compounds are characterized by transformation into their deuterio derivatives with deuterium oxide at low temperature.The thermal decomposition of these organometallic intermediates is also reported.The reactivity of the lithiated trianion derived from isopropylaniline (25a) with different agents (ethyl bromide, dimethyl disulphide, and trimethylchlorosilane) in a successive or simultaneous way is studied; this process occurs in a regioselective manner.
