摘要

Photolysis of 1-(3-alkynoxy)-9, 10-anthraquinones in deoxygenated methanol leads to moderate yields (35− 45%) of 3-alkynals along with the unexpected formation of diacetals. Reaction of these 3-alkynals with Grignard and Wittig reagents occurs nearly quantitatively without rearrangement to their 2, 3-dienal isomers.
