In combination with subsequent 5-endo-trig cyclizations geminally disubstituted dihydrofurans are accessible in high optical purity. Key words Key wordsallenes - axial chirality - desymmetrization - biocatalysis - 5-endo-trig cyclization Volltext Referenzen References 1a Koeller KM, Wong C.-H. Nature 2001; 409: 232 1b Faber K.

Tetrahedron Lett. 2000; 41: 9613 12 Especially the anisyl derivatives 2h and 3h showed high susceptibility to acid-catalyzed cycloisomerization. Obviously, even trace amounts of acid in the NMR solvent seem to favor cyclization as signals of the corresponding dihydrofuran appear as minor impurities in the NMR spectra; see the Supporting Information. 13a Marshall JA, Pinney KG.
