Acylation in Friedel-Crafts reactions

Metivier, P. Friedel-Crafts Acylation In Friedel-Crafts Reaction Sheldon, R. A. Bek-kum, H. eds., WUey-VCH New York. 2001, ppl61-172. (Review). 

Highly enantiosele ctive annulation reactions of (tert-butyldiphenylsilyl)allenes with ethyl glyoxylate using bis(oxazolinyl)pyridine-scandium triflate complex was described [120]. This [3 + 2] cycloaddition gave the corresponding dihydrofurans in moderate to high yields with high enantioselectivities (Scheme 12.54). The vinyl-silane functionality was acylated in Friedel-Crafts reaction with acetyl chloride to produce a-alkoxyenone.
