Abstract
Reaction of aldehydes (prim-, sec-, and tert-) with diazoacetamide (8,
9) of N-substituted glycinate in the presence of Zr(IV) chloride in C
H2Cl2 affords beta-keto amides (11, 12) in good to high yields, which
on treatment with n-Bu4NF in THF are led to N-protected 3-acyltetramic
acids (13, 14).
