The flavan-isoflavan rearrangement: Bioinspired synthetic access to isoflavonoids via 1,2-shift-alkylation sequence

An approach to 2-substituted isoflavonoids is reported based on the 1,2-shift of the aryl group in the catechin skeleton followed by the in situ alkylation. Synthesis of (-)-equol, a natural isoflavan with estrogenic activities, was achieved.

Synthesis and Crystal Structure of Li2 - a Dilithiomethane Derivative?

Reaction of (trimethylsilyl)methyllithium with the methylene-bridged aluminium tetrachloride Cl2Al-CH2-AlCl2 yields dilithium methylenebis (2) as the only isolable product.All attempts for preparing the tetraalkyl analogue have been unsuccessful.The crystal structure of 2 exhibits a hexacoordinated central carbon atom with short Li-C distances.Both lithium atoms and the methylene hydrogens of the Al-CH2-Al unit are almost coplanar.The discussion of the structure and properties leads to the attractive description of 2 as an adduct of tris(trimethylsilylmethyl)aluminium to dilithiomethane CH2Li2. Key Words: Dilithium bis(aluminate), methylene-bridged / Hexacoordinated carbon atom / / Dilithiomethane derivative

Attempted syntheses of low-oxidation-state organometallic derivatives of aluminum, gallium, and indium. A new synthesis of Al(CH2SiMe3)3

The synthesis of KAl(CH2SiMe3)2 by a reductive-elmination reaction between Al(CH2SiMe3)3 and KH has been attempted, but a pure product could not be isolated. The reactants combine at 70°C to form KAl(CH2SiMe3)3H, a white pyrophoric solid, which has been fully characterized. A molecular weight study indicates the presence of a mixture of monomeric and dimeric species in benzene solution. The pyrolysis of KAl(CH2SiMe3)3H at 205°C produces Si(CH3)4 but also CH4. The formation of Si(CH3)4 suggests that KAl(CH2SiMe3)2 might have been formed, but the presence of CH4 indicates that a decomposition reaction occurs either prior to or after the formation of KAl(CH2SiMe3)2. The reactions of mixtures of KH-Al(CH3)3, KH-Ga(CH3)3, NaH-Ga(CH3)3, KH-In(CH3)3, and NaH-In(CH3)3, have also been investigated in order to determine the role of the organic substituent in the attempted reductive-elimination reactions. In all cases the formation of CH4 during pyrolysis of KAl(CH3)H, KGa(CH3)3H, and the other reaction mixtures is consistent with the occurrence of reduction, but no pure compounds could be isolated. A new synthetic route to Al(CH2SiMe3)3 from AlBr3 and LiCH2SiMe3 in refluxing hexane is also described.
