✦ Synopsis

The stereoselective preparation of 1-hydroxycyclopenta-precursors are easily synthesized by two consecutive enolate alkylations. Excellent stereochemical control for the necarboxylic acid derivatives is reported. The key reaction is either a radical cyclization or a radical annulation mediated quaternary C(1) stereogenic center has been achieved. by the transfer of a phenylseleno group. The radical

During the past decade, important advances have been made in the understanding of the hydrolytic degradation characteristics of aliphatic polyesters derived from lactic acid (LA) and glycolic acid (GA). Degradation of large poly(LAGA) (PLAGA) polymers is autocatalyzed by carboxyl end groups initiall
