A carbene-catalyzed oxidative [3+3] cycloaddition reaction between enals and nitrogen ylides for quick access to 2-pyrones I [R = Et, Ph, 2-naphthyl, etc.; Ar = Ph, 4-BrC6H4, 2-furyl, etc.] was reported. Inexpensive and easily prepared 2′-pyridinium bromide salts were used as precursors of pyridinium ylides to react with enals in this catalytic reactions.
Asian Journal of Organic Chemistry published new progress about [3+3] Cycloaddition reaction. 3893-18-3 belongs to class bromides-buliding-blocks, and the molecular formula is C9H7BrO, Recommanded Product: 3-(4-Bromophenyl)acrylaldehyde.
