Synthesis and optical resolution of the neurotoxin 2‐amino‐3‐([¹⁵N]‐methylamino)propanoic acid (BMAA)

Journal of Labelled Compounds and Radiopharmaceuticals (1990)

Abstract The synthesis of 2‐amino‐3‐([ 15 N]‐methylamino)propanoic acid (synonyms, BMAA, β‐N‐methylamino‐alanine) from α‐acetamidoacrylic acid and [ 15 N]‐methylamine is described. Enantioselective hydrolysis of the acetamide group, mediated by the enzyme Acylase 1 (EC 3.5.1.14), yielded (R)‐BMAA and the (S)‐α‐acetamido derivative. Acid hydrolysis of the latter compound yielded (S)‐BMAA.

Simultaneous inversion of configuration of both the chiral ring and the carbinol carbon in (E)-(1 R,2R)-cyclo-oct-2-en-1-ol

Journal of the Chemical Society Chemical Communications (1990)

Ayala Balan Herman Ziffer

The reaction of (–)-(E)-(1 R,2R)-cyclo-oct-2-en-1-ol with p-bromobenzoic acid under Mitsunobu reaction conditions yields the corresponding p-bromobenzoate with simultaneous inversion of configuration of both the chiral ring and the carbinol carbon.
