Stereospecific Synthesis of Allenes from β‐Ketosulfones
نویسندگان
چکیده
Abstract Enolates formed from 1‐phenyl‐5‐tetrazolyl β‐ketosulfones containing a tetrasubstituted α carbon centre undergo elimination to allenes with up four substituents at the cumulene unit when treated weak base (phenolate) in DMSO room temperature. The reaction is completely regioselective for allene vs diene formation nearly all investigated cases and it proceeds central‐to‐axial chirality transfer. magnified image

Direct and stereospecific synthesis of allenes via reduction of propargylic alcohols with Cp2Zr(H)Cl.
Allenes can be synthesized via the direct SN2' addition of hydride to propargylic alcohols. Previous examples of this approach, however, have involved harsh reaction conditions and have suffered from incomplete transfer of central chirality to axial chirality. Here we show that Cp2Zr(H)Cl can react with the zinc or magnesium alkoxides of propargylic alcohols to generate allenes in good yield an...

Regioselective addition of aryl lithium to commercially available (S)-(+)-propylene oxide provides the corresponding (S)-aryl-2-propanol. The (R)-amphetamine is obtained by conversion of the alcohol to the tosylate followed by azide displacement and hydrogenation. Mitsunobu conversion of the alcohol to the (R)-bromide followed by azide displacement and hydrogenation affords the (S)-amphetamine....
متن کاملAmbiphilic allenes: synthesis and reactivity.
Ambiphilic allenes are generated by an organocatalyzed domino reaction of alkyl propiolates and aromatic 1,2-diketones; in the absence of any external chemical agent, these allenes perform a thermally-driven dimerization reaction to generate the corresponding fully-substituted cyclobutanes in a regio- and highly stereoselective manner.
متن کاملTotal synthesis of stereospecific sphingosine and ceramide.
A small-scale synthesis of the four sphingosine stereoisomers (d-erythro, l-erythro, d-threo, and l-threo) and lignoceroyl d- and l-erythro-sphingosines, which is suitable for synthesis of tritium-labeled compounds, is described. Ethyl dl-erythro-2-acetamino-3-hydroxy-4t-octadecenoate was esterified with l(+)-acetylmandeloyl chloride and the two diastereomers obtained were separated from each o...
