World number one Woods, looking for his sixth win of 2013, had surged to within one shot of the lead in Antalya with a best-of-the-week 63 in the second round on Friday.
The American continued to look in good touch on his reappearance after a month away from competitive action on Saturday - pitching to a couple of feet on the first and striking fine approaches to the third and eighth holes for birdies.
At 14 under par he was tied for second with Ian Poulter, Raphael Jacquelin and Alejandro Canizares, but Dubuisson surged clear with a brilliant outward 30 that included four birdies in his first four holes.
The 23-year-old Frenchman has never finished better than third on the European Tour, but at 17 under he was keeping some of the world's best golfers at bay.
Ryder Cup star Poulter, who was part of a four-way tie for the halfway lead, went to the turn in 33 and in doing so boosted his chances of catching Henrik Stenson in the Race to Dubai standings.
The pair have placed a financial wager on which will finish the year as European number one and made a bet that the loser will pour drinks on a night out at the end of the season.
The Englishman needs to close a gap of more than £450,000 with only next week's DP World Tour Championship to come, but had a chance to do so this week as Stenson failed to capitalise on a fine start.
The Swede birdied the first two holes at the Montgomerie Maxx Royal, but then dropped a shot at the seventh to find himself sixth on 13 under, one behind Poulter and Woods.
Dubuisson's compatriot Jacquelin equalled the European Tour record of 12 birdies in a single round, four of them coming in succession over the last four holes, as he carded a best-of-the-week 62 to set the clubhouse target at 15 under.
That was two behind Dubuisson, who started for home with three straight pars, while Woods also moved to within two with a birdie at the long 13th.
Poulter, Stenson and Canizares were all a shot further back on 14 under.
