Paragraph 0071-0073; 0076; 0077, (2016/10/10)
The present invention relates to a one-pot synthesis method of dihydrofuran derivatives using a ruthenium catalyst and, more particularly, to a one-pot synthesis method of dihydrofuran derivatives, which makes a reaction between cyclic/non-cyclic diazo dicarbonyl compound and olefin in the presence of ruthenium (II) phosphine complex as a reaction catalyst. The one-pot synthesis method of the present invention shortens time required for the reaction and improves synthesis yield. The diazo carbonyl compound represented by chemical formula 1, 2, or 3 reacts with olefin to form dihydrofuran derivatives through a [3+2] cyclization addition reaction.COPYRIGHT KIPO 2016

A novel and efficient method for the synthesis of 2,3-dihydrofurans bearing a variety of substituents on the dihydrofuran ring was achieved by the reaction of cyclic diazodicarbonyl compounds with styrene and vinyl acetate. The key strategy was AgBF4
