Burak Yılmaz's late penalty miss proved costly as Turkey fell to a 3-1 loss to Portugal in their 2022 World Cup qualifying play-off semi-final on Thursday.
Otavio scored his second international goal in just his third cap to put Portugal in front, with Diogo Jota doubling their advantage before half-time.
Yılmaz pulled one back for Turkey after the hour mark and had a chance to take the game to extra time by making it 2-2 after referee Daniel Siebert awarded the visitors a penalty for Jose Fonte clipping Enes Ünal.
However, Yılmaz's spot-kick clipped the crossbar on its way over and Matheus Nunes rubbed salt into the wound in stoppage time, ensuring it was Portugal who advanced to the final against North Macedonia, who earned a shock 1-0 triumph over European champions Italy.
Portugal started brightly and took the lead when Otavio scored on the follow-up after Bernardo Silva's shot was tipped onto the post by Uğurcan Çakır.
Turkey responded positively to going behind but Portugal doubled their advantage before half-time when Jota guided Otavio's exquisite delivery into the bottom-right corner with a pinpoint header.
Yılmaz pulled one back for Turkey when he stabbed a cool finish past Diogo Costa in the 66th minute after an excellent one-two with Cengiz Ünder.
The game looked destined to be heading for extra time when the referee pointed to the spot after a trip to the pitchside monitor with five minutes remaining, but Yılmaz was unable to convert.
It proved to be Turkey's undoing as substitute Matheus put the result beyond doubt when he finished off a pass from Rafael Leao in the 94th minute to send Portugal through.
