| Abstract: |  -Alkyl
chalcones 3a-d on acid catalyzed
cyclization give a mixture of (±) trans and (±) cis 2-aryl-3-alkylchroman-4-ones.
cis 4a-d are converted to trans
5a-d by epimerization with dil.
alkali. a-Aryl chalcones 3e-h on acid catalyzed cyclization give (±) trans
2,3-diaryl-chroman-4-ones 5e-h. On
NaBH4 reduction 5a-h give
(±) 2,3-trans-3,4-trans-2-aryl-3-alkyl/aryl- chroman-4-ols
6a-h. |
