Abstract 2- hydroxy, 3- hydroxy, 4- hydroxypyrans and 3- hydroxy -2,2 - dideutero tetrahydropyRan have been prepared in order to determine the conformation of the c-oh bond. The imino-esters and keto-imines are prepared in order to prepare optically active aziridine . The proportion and separation of the diastereoisomers of aziridine esters have beEn accomplished by nuclear magnetic resonamce , gas and liquid phase chromatography and infra-red spectroscopy . Oxaziridines have been prepared by oxidation of imino-esters and ketoimines by peracids. |
