Metal-free condensation reaction of glyoxylic acid acetalde with aryl isothiocyanates leading to α-acetal amides has been reported. The present protocol, which simply utilizes 1,8-diazabicyclo(5.4.0)-undec-7-ene (DBU) as base, provides a green and efficient approach to construct a series of α-acetal amides in the absence of metal catalysts and stoichiometric amounts of coupling reagents.

Key words: metal-free, α-acetalamide, glyoxylic acid, aryl isothiocyanate
