- 中文摘要: Several new coumarinyl crotononitriles, 2a-i, coumarinyl cinnamocoumarines 3a,b, 4-amino-3-(substituted)-3,4-dihydrocoumarin 4a-c and 9a-c, nicotinic acid derivatives 10a,b and 4-ethoxy-3-substituted-3,4-dihydrocoumarins 11, were synthesized from 3-acetyl and/or 3-benzoyl coumarin. The behavior of coumarin-3-yl crotononitriles 2a,b toward some electrophilic and nucleophilic reagents have been described with the aim of preparing some new heterocyclic compounds.
