alpha-Amino Acids as Chiral Educts for Asymmetric Products. The Synthesis of alpha’-Amino-alpha,beta-ynones
alpha-Amino acid isoxazolidides have been developed as educts for the preparation of optically pure alpha’-amino-alpha,beta-ynones.The alpha-amino acids were first N-protected as their ethoxycarbonyl, tert-butoxycarbonyl, or phenylsulfonyl derivatives.The isoxazolidides then were formed by the simple, high yield acylation of isoxazolidine by in situ generated alpha-amino acid isobutyl carbonic anhydrides.Individual isoxazolidides of L-alpha-N-substituted alanine, phenylalanine, and methionine, when treated with lithium acetylide, lithium (trimethylsilyl)acetylide, or 1-hexynyllithium, gave high yields of the corresponding optically pure alpha,beta-acetylenic ketones.
A reaction mechanism is the microscopic path by which reactants are transformed into products. Each step is an elementary reaction. In my other articles, you can also check out more blogs about 39657-45-9
