Speculation has continued to place the former Dutch international on the list of candidates for the Spurs job after last weekend's departure of Andre Villas-Boas.
He had one day earlier said he would have been "honoured" by the interest from the Premier League club. "It means I have good standing. But I am staying at Ajax," he said after Thursday's 3-0 club win over amateurs Ijsselmeervogels.
"Spurs are not a club I'm interested in moving to at the moment. But I think they are certainly a great club. Just as it was with Liverpool, it is to do with the timing. But I'm not finished at Ajax."
De Boer is chasing a record fourth successive Dutch league title and this season's Europa League title.
Last year the 43-year-old, who played at Ajax, Barcelona, Galatasaray and Scottish club Rangers, had a discussion with Liverpool about the manager's job at Anfield. He has since signed a contract until 2017 with Ajax.
