The ammonia/formaldehyde couple (the ugly duckling in Ugi reactions) was finally made possible using hexamethylenetetramine (HMTA) as an efficient formaldehyde surrogate. Various NH-free Ugi adducts were obtained in moderate to excellent yields and two of them were converted to diketopiperazines (DKPs).
