Abstract:
A method of manufacturing 1-indanone comprising the steps of reacting an indanyl ether represented by generic formula (I) ##STR8## (where, in the formula, R is a straight-chain or branched-chain lower alkyl group with a carbon number of 1-5 or an alkoxyalkyl group represented by CH(OR.sub.2)R.sub.1 ; R.sub.1 and R.sub.2 are straight-chain or branched-chain lower alkyl groups with a carbon number of 1-5; R.sub.1 and R.sub.2 may be identical or different; R.sub.1 and R.sub.2 may also be connected to form a ring; X is a halogen atom or substituent sulfonyloxy group represented by OSO.sub.2 R.sub.3 ; R.sub.3 is a substituent or non-substituent phenyl group or a lower alkyl group with a carbon number of 1-5; OR and X may have the cis- arrangement or the trans- arrangement; and it may be in racemic form or optically active form) under basic conditions to give an indenyl ether derivative represented by generic formula (II) ##STR9## (where, in the formula, R is defined identically to that in generic formula (I) above) and hydrolyzing this to give the 1-indanone represented by generic formula (III) ##STR10##
