The present invention relates to compound of formula I, which are functionalized, non-phenolic amino acids, and polymers formed from the same.
Polymers formed from the functionalized amino acids are expected to have controllable degradation profiles, enabling them to release an active component over a desired time range. The polymers are also expected to be useful in a variety of medical applications.

Rhodium-mediated cyclization of the alpha-diazo ester 1 proceeds with high diastereoselectivity, to give the trisubstituted cyclopentane 5. A computational model (ZINDO and Molecular Mechanics) based on our current mechanistic understanding of the reaction is presented. This model correctly predicts the dominant diastereomer from the cyclization of 1 and the eight (Table 2) other alpha-diazo esters studied thus far.
