The present invention relates to tricyclic compounds each represented by the following formula (I):
(wherein, R1, R2, R2', R3, R4, X, Y and Z have the same meanings as defined in the specification); and a drug containing the compound.
Since the compounds according to the present invention exhibit an excellent squalene synthetase inhibitory effect and cholesterol synthesis inhibitory effect so that they are useful as a drug such as preventive and/or remedy for diseases in mammals including humans such as hyperlipemia, e.g., hypercholesterolemia, hypertriglyceridemia, and low HDL cholesterolemia and/or arteriosclerosis.
Provided are compounds of the formula (I)
which are suitable for controlling animal pests, including arthropods and in particular insects, arachnids and nematodes, and in which the structural elements R

Oxidative free-radicalcyclization of α-chloromalonate 9 with Mn(OAc)3·2H2O and Cu(Oac)2·H2O in acetic acid at 75 °C provides 82% of lactones 10a and 10b. Hydroboration of 10 followed by oxidation affords acids 12, which are converted to avenaciolide precursor 15 in 32% overall yield from 9 by decarboxylation and cyclization.
What are demonstrated are compounds of the formula (I)
which are suitable for controlling animal pests, including arthropods and especially insects, arachnids and nematodes, and in which the structural elements Q
