THE INFLUENCE OF α-ARYL ETHERS ON THE ASYMMETRIC REDUCTION OF CARBONYLS
Samuels, William D.,Nelson, David A.,Hallen, Richard T.
, p. 3091 - 3094 (2007/10/02)
The asymmetric reduction of α-aryl ethers 1 was found to be strongly influenced by the presence of ortho substituents on the aryl ring.Groups (methoxy or hydroxy) that chelate metal cations tend to stabilize a "locked" bicyclic 4 which, intermediate when
Asymmetric Synthesis of 3-methyl-2-phenyl-1,4-benzodioxanes. Absolute Configuration of the Neolignans Eusiderin and Eusiderin C and D
Arnoldi, Anna,Merlini, Lucio
, p. 2555 - 2558 (2007/10/02)
The asymmetric synthesis of 2S,3S- and 2R,3S-3-methyl-2-phenyl-1,4-benzodioxane from (-)-ephedrine is reported.Comparison of the c.d. curves of these compounds with those of the natural neolignans eusiderin and eusiderin C allows the assignment of 2R,3R configuration to eusiderin and of 2R,3S configuration to eusiderin C and eusiderin D.
Stereospecific Synthesis of 2,3-Disubstituted 1,4-Benzodioxans
Proietti, Gabriele,Corsano, Stefano,Castagnino, Enzo
, p. 415 - 416 (2007/10/02)
The synthesis of cis- and trans-2-methyl-3-phenyl-1,4-benzodioxans 4 and 5, from 1-phenyl-2-propanols threo 2 and erythro 3 are described.
