Literature References

2-Lithiothiazole can be obtained by direct lithiation of thiazole or, more conveniently, by exchange with 2-bromothiazole using n-BuLi: J. Org. Chem., 53, 1748 (1988). It behaves as a valuable formyl anion equivalent, and as such has been applied, mainly by Dondoni's group, in the syntheses of a variety of products; see, e.g.: Tetrahedron Lett., 34, 7319, 7323, 7327 (1993). See also 2-(Trimethyl­silyl)­thiazole, B21903. Reaction of 2-lithiothiazole with nitrones gives ɑ-aminoaldehydes: Tetrahedron Lett., 33, 4221 (1992); stereocontrolled addition to C-galacto-pyranosylnitrone has been used in syntheses of destomic acid, a component of the antibiotics destomycin and hygromycin, and of lincosamine, the sugar component of the anticancer antibiotic lincomycin: Synlett, 78 (1993). For applications of 2-lithiothiazole in the synthesis of the aza-sugar (+)-galactostsin, see: J. Org. Chem., 60, 4749 (1995). The Thiazole Aldehyde Synthesis has been reviewed by Dondoni: Synthesis, 1681 (1998).
