Abstract :
Reactions of N-, C-, and S-nucleophiles with 3-nitro-2-trifluoro(or trichloro)methyl-2H-chromenes proceeded via nucleophilic addition at the double bond to give 2,3,4-trisubstituted chromans in good tomoderate yields. Stereochemical and conformational preferences of 2,3,4-trisubstituted chromans were studied.
