The invention provides a preparation method of an intermediate compound 7 of an SGLT-2 diabetes inhibitor dapagliflozin and an intermediate compound 8 of a SGLT-2 diabetes inhibitor empagliflozin, and new synthesis method of two final products. The preparation method comprises the following steps: carrying out carbonyl group reduction and hydroxyl group protection on a (5-halo-2-chlorophenyl)(4-ethoxyphenyl)ketone compound 1 used as an initial raw material to obtain a Grignard addition reaction key compound 4, and carrying out Grignard addition and acetylation to obtain the compound 7 and the compound 8. The dapagliflozin and the empagliflozin are respectively prepared from the compound 8. The methods have the advantages of simplicity in operation, high yield, high purity of the obtained products, and suitableness for amplified production.
