4-Methyl-5-phenyl-1,3-oxazolidine is a recreational designer drug with stimulant effects. It is the ring-contracted analogue of phenmetrazine, having a 5 membered oxazolidine ring in place of the 6 membered morpholine core of phenmetrazine, and has similar stimulant effects with only slightly lower potency, though less chemical stability due to the acid-sensitive oxazolidine ring.
