Abstract

Vast methodology exists in the literature for the synthesis of cr-amino acids and their derivatives. However, there is a paucity of information pertaining to the chemistry of unnat. ura1 cyclic amino acids, specifically those with a nitrogen--oxygen bond to the carboxylate function. We were interested in an unambiguous synthesis of~~-tetrahydro-2H-1, 2-oxazine- 3-carboxylic acids (la, R
