title: One-pot four-component synthesis of pyrimidyl and pyrazolyl substituted azulenes by glyoxylation-decarbonylative alkynylation-cyclocondensation sequences.
abstract: A novel one-pot four-component synthesis of pyrimidyl- and pyrazolylazulenes through the use of glyoxylation-decarbonylative alkynylation-cyclocondensation sequences starting from azulene or guaiazulene as substrates, gives rise to the formation of the target compounds in moderate to good yields.
