Did you get an email with a ticket number? You should receive two emails -- the first, that shows your reservation, does not mean that your flight has been confirmed. The partner airlines have 24 hours to confirm your reservation; if they no longer have space, the flight cannot be ticketed.

Assuming that you did get a ticket, UA has two options: give you a full refund, or get you to your destination. UA can open award space on its
own flights, but not on partners. Do an award search on the day you'd like to travel, from DPS to SIN, and see what shows up in business class, ignoring the number of miles required. You should be able to change to any of those options at no charge. You could also potentially drop a problematic segment, so if only DPS-BKK is a problem, you could just drop that and start from BKK.
If SQ is still flying DPS-SIN, then DPS-SIN-SFO is likely a possibility, with DPS-SIN on SQ and SIN-SFO on UA.
