Lipase-catalyzed desymmetrization of quaternary carbon-containing 1,3-propanediols: A new entry to the asymmetric synthesis of α-substituted serine analogues

A new approach to the asymmetric synthesis of α-substituted serine analogues was developed. The method utilizes a lipase-catalyzed esterification desymmetrization protocol. In the presence of PPL, a series of benzyl-substituted quaternary 2-nitropropane-1

A convenient transformation of α-alkylserines into α-halogenomethyl-α-alkylglycines

An efficient and facile synthesis of N-Boc-α-chloromethyl- and α-bromomethyl-α-alkylglycines is reported that involves cyclization of N-Boc-α-alkylserines to the corresponding β-lactones under Mitsunobu reaction conditions, followed by ring opening with anhydrous MgCl2 or MgBr2.

Asymmetric Syntheses of Both Enantiomers of α-Benzylserine and α-Carboxymethylserine

Both enantiomers of α-benzyl and α-carboxymethyl serines (1, 2) were efficiently synthesized starting with the known phenyl acetol via an intramolecular asymmetric Strecker synthesis.
