A convenient synthesis of optically active N-(o-carboxybenzoyl)-L-amino acids

Optically active N-(o-Carboxybenzoyl)-amino acids, derived from L- phenylalanine, L-leucine and L-valine, were prepared in reasonably good yields and high optical purities.

1-PYRENYLMETHYL ESTERS, PHOTOLABILE PROTECTING GROUPS FOR CARBOXYLIC ACIDS

1-Diazomethylpyrenes were prepared and reacted with carboxylic acids to give 1-pyrenylmethyl esters.The fluorescent esters were photolysed at 340 nm in methanol to form the starting acids and the corresponding 1-methoxymethylpyrenes in high yields.
