Biginelli reaction of thiourea, 2-hydroxy-1-naphthaldehyde, and acetoacetic ester (or benzoyl acetone) under solvent-free conditions and MW irradiation gave novel 3-thioxo-2,3,4,5-tetrahydro-1H-1,5-methanonaphtho[1,2-g][1,3,5]oxadiazocine derivatives. Subsequent reaction of the obtained compounds with α-chloroacetamide led to 5-methyl-5H,13H-5,13-methanonaphtho[1,2-g] thiazolo[2,3-d][1,3,5]oxadiazocin-1(2H)-ones, which were converted to the Z-isomers of 2-arylylidene-5H,13H-5,13-methanonaphtho[1,2-g]thiazolo[2,3-d][1,3,5]oxadiazocin-1(2H)-one derivatives by reaction with arylaldehydes. The structures of the products were characterized by 1H NMR, 13C NMR spectra, and X-ray analysis.
