The title compound, C19H17PS2, results from the direct deprotonation of di-phenyl-methyl-phosphine sulfide and subsequent reaction with diphenyl di-sulfide. The C-P and C-S bond lengths of 1.8242 (18) and 1.8009 (18) Å, respectively, of the central P-C-S linkage are comparable to those found in the sulfonyl analogue, but are considerably longer than those reported for the dimetallated sulfonyl ...

Bioassay-guided fractionation of metabolites from the fungus Cephalosporium sp.AL031 isolated from Sinarundinaria nitida led to the discovery of a new isobenzofuranone derivative, 4,6-dihydroxy-5-methoxy-7-methylphthalide (1), together with three known compounds: 4,5,6-trihydroxy-7-methyl-1,3-dihydroisobenzofuran (2), 4,6-dihydroxy-5-methoxy-7-methyl-1,3-dihydroisobenzofuran (3) and 4,5,6-trihy...

In the title compound, C17H21BrO2S, the cyclo-hexyl ring adopts a chair conformation and the aryl-sulfinyl unit is positioned equatorially relative to the cyclo-hexyl group. The benzo-furan unit is essentially planar, with an r.m.s. deviation of 0.016 (2) Å. In the crystal, mol-ecules are linked by weak C-H⋯O, C-H⋯π and Br⋯π [3.663 (2) Å] inter-actions, resulting in a three-dimensional network....

An increasing number of reactions of sulfenic acid anions are being demonstrated in the literature. As such, mild, general and reliable means for the generation of sulfenates are due. In the current paper, an addition/elimination of 2-sulfinyl acrylates using various nucleophiles is demonstrated and evaluated as a protocol for alkane- and arenesulfenate generation. Cyclohexanethiolate, methoxid...

Two new carbapenem antibiotics, carpetimycins C and D have been isolated from the culture broth of Streptomyces p. KC-6643, which produced carpetimycins A and B. The structures of carpetimycins C and D have been determined to be (5R,6R)-3-[2-acetamidoethyl(R)-sulfinyl]-6-(1-hydroxy-l-methylethyl)-7-oxo-l-azabicyclo[3.2.0]hept-2-ene-2-carboxylic a id and (5R,6R)-3-[2-acetamidoethyl-(R)-sulfinyl]...

In the title compound, C26H23NO2, the dihedral angles between the pyrrole ring and the two phenyl rings are 58.1 (6) and 71.5 (5)°. The mean planes of the 5-methyl-benzene ring and the carboxyl group are twisted by 89.5 (3) and 22.1 (9)°, respectively, from the pyrrole ring. In the crystal, weak C-H⋯O inter-actions lead to supra-molecular layers in the ab plane.

In the title compound, C(21)H(15)ClO(2)S, the O atom and the phenyl group of the phenyl-sulfinyl substituent lie on opposite sides of the plane of the benzofuran fragment; the phenyl ring is almost perpendicular to this plane [82.24 (7)°]. The phenyl ring in the 2-position is rotated out of the benzofuran plane, making a dihedral angle of 11.50 (9)°. The crystal structure is stabilized by inter...

In the title hydrate, C(16)H(15)BrO(2)SSe·H(2)O, the sulfinyl O atom lies on the opposite side of the mol-ecule to the Se and carbonyl O atoms. The benzene rings form a dihedral angle of 51.66 (17)° and are splayed with respect to each other. The observed conformation allows the water mol-ecules to bridge sulfinyl O atoms via O-H⋯O hydrogen bonds, generating a linear supra-molecular chain along...

The reduction using phenylsilane in a KOH-catalyzed system was applied successfully to the conversion of sulfinyl-substituted cyclopropylcarboxylates into the corresponding alcohols. The presence of sulfinyl substituents in the α-position to the carboxylate group caused a desulfinylation product formation with full regio- and stereoselectivity, instead of a carbonyl group reduction. Investigati...

Mannich-type reactions of O-Boc glycolic esters across chiral N-sulfinyl-α-chloroaldimines resulted in the efficient and syn-stereoselective synthesis of new γ-chloro-α-hydroxy-β-amino esters (dr > 99 : 1). The α-coordinating ability of the chlorine atom was of great importance for the diastereoselectivity of the Mannich-type reaction and overruled the chelation of the sulfinyl oxygen with the ...
