Compared with the ripeness of olefin metathesis, exploration of the construction of carbon–carbon double bonds through the catalytic carbonyl–olefin metathesis reaction remains stagnant and has received scant attention. Herein, a highly efficient AuCl3-catalyzed intramolecular ring-closing carbonyl–olefin metathesis reaction is described. This method features easily accessible starting materials, simple operation, good functional-group tolerance and short reaction times, and provides the target cyclopentenes, polycycles, benzocarbocycles, and N-heterocycle derivatives in good to excellent yields.

, (2020/01/07)
The present invention relates to a novel synthesis method of 3,10-disubstituted benzofulvene derivatives which is excellent in an economic aspect since the yield is excellent. The novel synthesis method comprises the steps of: synthesizing an indene derivative having an enamine substituent; synthesizing an intermediate compound represented by chemical formula A; synthesizing an intermediate compound represented by chemical formula B; and synthesizing a 3,10-disubstituted benzofulvene derivative represented by chemical formula 3.COPYRIGHT KIPO 2020

Upon reaction with an excess of 2,2-dimethylpropane-1,3-diol (neopentyl glycol, NPG) under acid catalysis, indanones and tetralones yield indenes and dihydronaphthalenes, respectively. The reaction can also be carried out with butane-1,3-diol.
