developed a simple and an efficient route to a range of angularly fused spirocycles by the application of enynemetathesis and the Diels–Alderreaction as keysteps. The enynemetathesis protocol has been further extended to the dibenzylation of indane-1,3-dione by using cross-enyne metathesis in the presence of hexa-1,5-diene with the aid of Grubbs’ 1st generation catalyst followed by an aromatization
