Abstract
Preparation process for 2-alkylindane of formula (IV) ** (See formula) ** wherein R represents a group selected from the linear or branched C1-C5 lower alkyl group and the C3-C7 cycloalkyl group, characterized in that: a) An aromatic ring of formula (I) is condensed: ** (See formula) ** wherein R has the same meaning as above with formaldehyde or a formaldehyde precursor in basic medium and in a polar organic solvent, with a view to obtaining a ketol of formula (II) ** (See formula) ** where R has the same meaning as above, b) the mentioned ketol of formula (I) is cyclized in a strong acid medium with a view to obtaining indanone of formula (III): ** (See formula) ** where R has the same meaning as above, c) the mentioned indanone is reduced with a view to obtaining the desired 2-alkylindane.
