Abstract

The trans,trans-2,3,4-trisubstituted chromans, previously described by us as addition products of acetoacetic ester or acetylacetone at the activated double bond of 2-substituted 3-nitro-2Н-chromenes, are axially chiral molecules due to the hindered rotation around the C(sp3)–C(sp2) bond.
