Abstract: Arylpyran pseudoacids showed slow ring-opening to the oxocarboxylic acids, and fast ring-closure to the lactols (pseudoacids) in a process that amounts to racemization. Compounds studied were patterned on “Cooper’s Pseudoacid” [3-hydroxy-4,4-dim

Abstract This Letter describes the use of NbCl5 as the Lewis acid in Friedel-Crafts reactions, in which a bifunctional electrophile reacts inter- and intramolecularly with an aromatic ring to produce a number of indanones in a single step, main

1-Indanones of the formula III or IIIa STR1 in which R1 to R7 are preferably hydrogen or alkyl, or adjacent radicals R1 to R4 form a ring, are obtained in a one-step reaction by reacting a compound I STR2 with a compound of the formula II STR3 in liquid hydrogen fluoride.
