Abstract
Abstract Several N-acyl-β-hydroxyamino acids were prepared and treated with di-tert-butyl dicarbonate in the presence of 4-(dimethylamino) pyridine, followed by treatment with N, N, N′, N′-tetramethylguanidine to give the corresponding N-acyldehydroamino acids in good to high yields. These were then treated with I 2/K 2 CO 3 followed by 1, 8-diazabicyclo [5.4. 0] undec-7-ene. The methyl esters of N-acyldehydroaminobutyric acid gave the ...
