position of a tetrapeptide such as 1 led to a significant gain in the inhibitory enzymatic activity, as compared to the corresponding norvaline derivative 2, prompted a systematic study of substituent effects on the three-membered ring. We report herein that the incorporation of a vinyl group with the proper configuration onto this small cycle produced inhibitors of the protease with much improved in vitro

All four stereoisomers of the 2,3-methanoamino acids BOC-E-cyclo-Leu and BOC-Z-cyclo-Leu were prepared from the optically active diol 4 (and its enantiomer) derived from valine. The challenges associated with introducing protected amine functionalities cis to the side chain were overcome by using the vinylogous malonate synthon, dimethyl gluconate.
