Narrative:
While enroute the cabin started to decompress and cabin compressor oil low light illuminated within 20 NM of ZZZ. Advised ATC and requested descent; started descent. While performing loss of pressurization checklist; we observed low oil pressure warning light illuminate while oil temperature and pressure appeared normal. Right oil quantity gauge indicated 4 gallons which is above minimum required for dispatch. Preventative engine shutdown initiated by pilot flying. Engine shutdown checklist accomplished. Continued diversion to ZZZ with safe landing.
