Abstract

A facile formylolefination of a variety of aldehydes was achieved by using formylmethyltriphenylarsonium bromide with K 2 CO 3 (trace H 2 O) at room temperature to give highly stereoselectively (E) α,β-unsaturated aldehydes in excellent yields. ...

The product of Entry 9 gave satisfactory elemental analysis (±0.3%); 1 H NMR(60 MHz,CCl 4 , δ): 9.37(d, J=7.8 Hz, 1H), 6.68(dt, J=16, 7.0 Hz, 1H), ...
