2-Amino-7a-carbamoyl-3a-hydroxy-3a,4,5,6,7,7a-hexahydro-benzoxazole (1) and hydrogenperoxide rearrange to 2'-amino-cyclopentanespiro-5'-oxazolin-4'-one (5). 5 and aniline hydrochloride form the phenylaminoderivative 6, 5 and 2,5-dichlorophenylhydrazine hydrochloride form the 2,5-dichlorophenylhydrazinederivative 7. 5 and hydrochloric acid afford cyclopentanespiro-5'-oxazolidin-2',4'-dione (8).Hydrolysis of 5 or 8 furnish 1-hydroxy-cyclopentane-carboxylic acid (9).
