[(1R,3S)-3-(1,3-Dithian-2-yl)-2,2-dimethylcyclopropyl]diphenylmethanol
In the title compound, C22H26OS2, prepared from (–)-1R-cis-caronaldehyde, the 1,3-dithiane ring adopts a chair conformation. An intramolecular O—H⋯S hydrogen bond influences the molecular conformation. In the crystal, weak intermolecular C—H⋯S and C—H⋯O hydrogen bonds link the molecules into chains propagating along [010]
Palladium- and base-free synthesis of conjugated ynones by cross-coupling reactions of alkynylboronates with acid chlorides mediated by CuCl
Alkynylboronates can be employed as a practical and versatile precursor for a variety of pi-conjugated organic compounds. In the presence of Cu(I) salt, cross-coupling reactions of acid chlorides with alkynylboronates giving rise to the corresponding conjugated ynones takes place readily in aprotic polar solvents such as DMI under neutral conditions
