A novel and one step procedure for preparation of α-bromo-α,β-unsaturated carbonyl compounds

A new one step method is developed for the preparation of α-bromo-α,β-unsaturated carbonyl compounds in moderate to good yields from corresponding α,β-unsaturated carbonyl compounds using DMP [1,1,1-triacetoxy-1,1-dihydro-1,2-benziodoxol-3(IH)-one] and te

Synthesis of 1,3-thioxoketones from salicylaldehyde

A method for the synthesis of monothiodibenzoylmethanes was developed. The method involves a reaction of potassium thioacetate with 1-(2-hydroxyphenyl)-3- phenylpropynone prepared from salicylaldehyde.

A new synthesis of 5-arylbenzo[c]xanthones from photoinduced electrocyclisation and oxidation of (E)-3-styrylflavones

A new synthetic route to 5-arylbenzo[c]xanthones is -established. This was accomplished by use the Heck reaction of 3-bromoflavones with styrene derivatives, leading to (E)-3-styrylflavones with total diastereoselectivity. This transformation was greatly improved under microwave irradiation. The one-pot, photoinduced electrocyclisation of (E)-3-styrylflavones and further in situ oxidation of the cycloadduct leads to 5-arylbenzo[c]xan-thones. Georg Thieme Verlag Stuttgart · New York.

Facile synthesis of new substituted 3-aryl/heteroarylflavones by Suzuki-Miyaura coupling of 3-bromoflavone with substituted aryu heteroarylboronic acids

Flavones 7a-k having aryl and heteroaryl substituents at 3-position were synthesized in a Panasonic microwave-oven by Suzuki-Miyaura cross coupling reaction using 3-bromoflavone 5 and substituted aryl and heteroaryl boronic acids 6a-k with tetrakistriphenylphospine-palladium |(C6H 6)3P]4Pd as catalyst and N,N-dimethylformamide (DMF)+ H2O (9:4) as solvent, and aq.Na2CO3(2N) as base.
