Abstract
The present invention provides novel acyclic terpenes of the formula: ##STR1## which are useful as intermediates for the industrially advantageous production of sarcophytol A.
Claims1
An acyclic terpene of the formula:
- ##STR113## wherein R.sup.1 is ##STR114## (X is a hydroxy group, chlorine atom, --OC(O)R.sup.3 (R.sup.3 is a hydrogen atom, C.sub.1 -C.sub.4 alkyl or optionally substituted phenyl group), --SR.sup.4, --S(O)R.sup.4 (R.sup.4 is a C.sub.1 -C.sub.4 alkyl group or optionally substituted phenyl group), --NR.sup.5 R.sup.6, or --N(O)R.sup.5 R.sup.6
- (R.sup.5 and R.sup.6 are independently a C.sub.1 -C.sub.4 alkyl group or taken together form an alkylene ring)), ##STR115## (Y is a halogen atom), ##STR116## (R.sup.7 and R.sup.8 are independently a C.sub.1 -C.sub.4 alkyl group or taken together from an alkylene ring), ##STR117## (R.sup.9 is a C.sub.1 -C.sub.4 alkyl group), ##STR118## (R.sup.10 is a C.sub.1 -C.sub.4 alkyl group optionally substituted by a halogen atom or an optionally substituted phenyl group), or a formyl group;
- R.sup.2 is a cyano group, formyl group or CO.sub.2 R.sup.11 (R.sup.11 is a C.sub.1 -C.sub.4 alkyl group);
- and n is 0 or 1, with the proviso that when n is 0, R.sup.1 must be ##STR119## in which X is a hydroxy group, chlorine atom or --OC(O)R.sup.3.
