Narrative:
Pilot flying heard engines drop out of synchronization and noticed a spike in torque on E2. A drop in torque resulted immediately followed rapidly by a low oil pressure light on the right. Pilot flying pulled right power lever to verify the correct engine; then pilots agreed on the right stop and feather handle and pulled it. Pilot flying commanded pilot not-flying to request direct to [a nearby alternate]. Pilot not-flying completed all checklists and programmed the GPS for the appropriate visual approach. Aircraft was losing airspeed at FL180 so the crew requested 17;000 feet where the aircraft was able to maintain airspeed and altitude. Visually; we were clear of all terrain and the aircraft was performing well. The crew briefed other options if E1 were to fail. The resulting visual approach and landing were without incident.
