Crystal structures of methyl 3-(4-isopropylphenyl)-1-methyl-1,2,3,3a,4,9b-hexahydrothiochromeno[4,3-b]pyrrole-3a-carboxylate, methyl 1-methyl-3-(o-tolyl)-1,2,3,3a,4,9b-hexahydrothiochromeno[4,3-b]pyrrole-3a-carboxylate and methyl 1-methyl-3-(o-tolyl)-3,3a,4,9b-tetrahydro-1H-thiochromeno[4,3-c]isoxazole-3a-carboxylate

In the title compounds, C23H27NO2S, (I), and C21H23NO2S, (II), the pyrrole rings have envelope conformations with the C atom substituted by the benzene ring as the flap. In the third title compound, C20H21NO3S, (III), the isoxazole ring has a twisted conformation on the C—C bond substituted by the b...
