The one-pot synthesis of N-substituted (3-oxobutanyl)carbamates via the tandem condensation of primaryamines with methyl chloroformate, followed by the conjugate addition of the resulting carbamate with methyl vinyl ketone in the presence of Sn4+ modified zeolite Hβ (Hβ-SnA) at room temperature is described.
