Halohydrin dehalogenase from Arthrobacter sp. AD2 catalysed azidolysis of epoxides with high regioselectivity and low to moderate (S)-enantioselectivity (E?=?1–16). Mutation of the asparagine 178 to alanine (N178A) showed increased enantioselectivity towards styrene oxide derivatives and glycidyl ethers. Conversion of aromatic epoxides was catalysed by HheA-N178A with complete enantioselectivity, however the regioselectivity was reduced. As a result of the enzyme-catalysed reaction, enantiomerically pure (S)-β-azido alcohols and (R)-α-azido alcohols (ee???99%) were obtained.
Intramolecular reductive amination strategy to the synthesis of (R)-N-Boc-2-hydroxymethylmorpholine, N-(3,4-dichlorobenzyl)(R)-2-hydroxymethylmorpholine, and (R)-2-benzylmorpholine

A concise high yielding enantioselective synthesis of (R)-N-Boc-2-hydroxymethylmorpholine, N-(3,4-dichlorobenzyl)(R)-2-hydroxymethylmorpholine, and (R)-benzylmorpholine has been achieved by employing proline-catalyzed asymmetric α-aminooxylation of aldehyde and palladium-catalyzed intramolecular reductive amination of azido aldehyde as the key steps.
Exploring functional and molecular diversity with polymer-bound p-alkoxybenzyl ethers - Scope and applicaitons of preparatively useful organic reactions
Hanessian, Stephen,Xie, Fang
, p. 737 - 740 (2007/10/03)
Alcohols immobilized as p-alkoxybenzyl ethers on Wang resins have been subjected to a variety of chemical transformations based on existing functionality (enolate chemistry, carbonyl group reactivity, Mitsunobu inversion, ozonolysis, Heck reactions, etc.), in an effort to test the suitability of this novel resin-bound ether linkage. The modified substrate was released from the resin by mild acid treatment.

(R)-Epichlorohydrin has efficiently been converted to the hypotensive and antiepileptic compound, (R)-γ-amino-β-hydroxybutanoic acid (GABOB), in six steps in 57percent overall yield.
