Over the last three decades, the sulfinyl group has received considerable attention in asymmetric synthesis1‒5 as a chiral tool. The sulfinyl group is widely used as to bring about numerous asymmetric transformations. The effectiveness of the sulfoxide in diastereoselective auxiliary-induced reactions is mainly due to the steric and stereo electronic differences existing between the substituent...

Abstract Diphenylamine (DPA), formyl chloride, and sodium hydride (NaH) as raw materials synthesize methyldiphenylurea stabilizer by alkylation reaction. The physical chemical properties of were characterized nuclear magnetic resonance hydrogen spectrum (1HNMR), X-ray energy (EDS), Fourier transforms infrared spectroscopy (FT-IR) differential thermal analysis (DTA). Thermal Decomposition Experi...

In the title compound, C(24)H(15)BrO(2)S, the sulfinyl O atom and the phenyl group of the phenyl-sulfinyl substituent lie on opposite sides of the plane through the naphthofuran fragment. The phenyl ring is nearly perpendicular to the plane of the tricyclic naphthofuran system [81.77 (6)°] and is tilted slightly towards it. The 4-bromo-phenyl ring is rotated out of the naphthofuran plane by a d...
