Ethyl 6-methyl-4-[2-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)thiophen-3-yl]-2-thioxo-1,2,3,4-tetrahydropyrimidine-5-carboxylate

چکیده
A new Biginelli compound, C(18)H(25)BN(2)O(4)S(2), containing a boronate ester group was synthesized from a lithium bromide-catalysed reaction. The compound crystallizes with two independent mol-ecules in the asymmetric unit that differ mainly in the conformation of the ester functionality. The crystal structure is stabilized by inter-molecular N-H⋯O and N-H⋯S hydrogen bonds involving the 3,4-dihydro-pyrimidine-2(1H)-thione NH groups as donors and the carbonyl O and thio-phene S atoms as acceptors.

In the title compound, C12H14N2O2S2, the di-hydro-pyrimidine ring adopts a sofa conformation, with the C atom bearing the thienyl ring lying above the plane of the five remaining approximately coplanar (r.m.s. deviation = 0.0405 Å) atoms of the ring. The dihedral angle between the five near coplanar atoms of the ring and the thienyl ring is 89.78 (11)°. In the crystal, mol-ecules are linked int...

The complete mol-ecule of the title compound, C(28)H(28)B(2)Br(4)O(4), is generated by the application of a centre of inversion. In the mol-ecule, the BO(2) plane is perpendicular to that through the pyrene ring [dihedral angle = 86.27 (13)°]. In the crystal, mol-ecules stack into columns along the b axis, the closest contact between these being of the type C-Br⋯π.
