Chlorido[2,3,5,6-tetra-kis-(tert-butyl-sulfanylmeth-yl)phenyl-κ(3) S (2),C (1),S (6)]palladium(II) dichloro-methane monosolvate.

The title compound, [Pd(C26H45S4)Cl]·CH2Cl2, crystallizes with a disordered dichloro-methane solvent mol-ecule [occupancy ratio = 0.67 (4):0.33 (4)].

1,3-Bis[(tert-butylsulfanyl)methyl]-2,4,6-trimethylbenzene.

The complete mol-ecule of the title compound, C(19)H(32)S(2), is generated by crystallorgaphic twofold symmetry, with three C atoms lying on the axis. The C(ar)-C-S-C (ar = aromatic) torsion angle is 156.2 (2) °.

A short and practical synthesis of two Hagen's gland lactones.

A seven-step total synthesis of Hagen's gland lactones 1 and 2 starting from 1,2-O-isopropylidene-alpha-D-xylofuranose 3 is reported. The success of this short and practical synthesis depends on the use of two key reactions: a stereoselective nucleophilic substitution at the anomeric position of 5 and 6, which allowed the construction of the gamma-lactone ring, and an alkyl substitution reaction on tosylated compound 4, which permitted the carbon chain elongation of the tetrahydrofuran ring appendage at C-6.

(2S,4R,5S)-5-Allyl-4-hydroxy-tetra-hydro-2-furylmethyl p-toluene-sulfonate.

In the title compound, C(15)H(20)O(5)S, the tetra-hydro-furan ring shows an envelope conformation. The crystal packing is stabilized by an inter-molecular O-H⋯O hydrogen bond, generating a ribbon structure along the a axis. Two weak inter-molecular C-H⋯O inter-actions are also observed.
