Abstract
N-Aryl- and N,N-diethyl-3-oxobutanamides reacted with salicylaldehyde and N-phenylthiourea in ethanol in the presence of sodium hydrogen sulfate as catalyst to give the corresponding N-substituted 2-methyl-3-phenyl-4-sulfanylidene-3,4,5,6-tetrahydro-2H-2,6-methano-1,3,5-benzoxadiazocine-11-carboxamides.
