Abstract
Process for ring opening compounds of the formula ##STR1## in which R.sup.1 is heteroaryl or aryl, R.sup.2 is a leaving group, R.sup.3, R.sup.4, R.sup.5 and R.sup.6 are independently selected from hydrogen, alkyl, aralkyl, aryl, heteroaryl and alkenyl, provided that at least one of the groups R.sup.3 to R.sup.6 is other than hydrogen, by breaking the bond joining the carbon atom attached to R.sup.3 and the carbon atom attached to R.sup.6 in organic solution using silica, giving useful diene or allyl derivatives, certain of which are novel.
