Abstract
The tritiated juvenoids ethyl ydroxy-1-cycloheptylmethyl)phenoxy]ethyl }carbamate (1), -(trans-2-hydroxy-1-cyclohexylmethyl)phenoxy]ethyl N-e thylcarbamate (2) and ethyl ethyl-r-1-cyclohexylmethyl)phenoxy]ethyl}c arbamate (3) were prepared by Catalyzed Exchange in Solution with Gas on PdO/BaSO4. The high degree of regio- and stereoselectivity observed in the products by H-3 NMR is discussed in the terms of the stereoele ctronic requirements of the exchange reaction.
