Heterocyclic Building Blocks-Thiazole

In an article, published in an article,authors is Bach, Thorsten, once mentioned the application of 4175-77-3, Name is 2,4-Dibromothiazole,molecular formula is C3HBr2NS, is a conventional compound. this article was the specific content is as follows.4175-77-3

The difunctional substrate 2,4-dibromothiazole 2 was transformed into the title compounds 1 by consecutive Pd(0)-catalyzed cross-coupling reactions. Aryl zinc reagents which were prepared by ortho-lithiation of compounds 3 and subsequent transmetalation were used as carbon nucleophiles in the first coupling reaction. By this means, an aryl substituent was attached to the 2-position (50-62% yield). A succeeding cross-coupling with arylboronic acids 4 occurred at the 4-position of the intermediate 4- bromothiazoles 5 (76-97% yield). (C) 2000 Elsevier Science Ltd.

The oxoketene dithioacetals 1 undergo regioselective 1,2-addition with 2-lithiomethyl-4-methylthiazole (2a) and 2-lithiomethylthiazoline (3) to afford the carbinol acetals 4 which on borontrifluoride etherate assisted cyclization yield the corresponding substituted and annelated 3-methyl-5-methylthiothiazolo[3,2-a.] pyridinium tetrafluoroborates (5a-S, 8a, b, 10, 12) and the dihydro derivatives (23-25) respectively in good yields. The corresponding 2-methyl-5-phenylthiazole (16) however underwent both nuclear and side chain deprotonation and yielded a mixture of products under similar reaction conditions.

General procedure: A solution of the selected heterocyclic starting material (1.00 mmol) in THF (10 mL) and a solutionof isopentyl nitrite (141 mg, 1.20 mmol) in THF (10 mL) were both pumped at a flow rate of 0.25 mLmin1 with a Vapourtech ?Easy MedChem V3? system, meeting at a PTFE T-piece and the outputflowing through a 10.0 mL coil reactor maintained at 120 C, giving a residence time of 20 min.The pressure of the system was maintained at 7 bar with a back-pressure regulator. For compoundswhere an isolated yield was reported: the output mixture was concentrated under reduced pressureto give an oil (or powder). The oil (or powder) was purified using column chromatography withvarious mixtures of ethyl acetate and hexane as the eluent, or by recrystallisation using methanol, togive isolated compounds that showed no impurities by NMR spectroscopy. For compounds where aconversion was reported (due to volatility of products), the output mixture was carefully concentratedunder a reduced pressure of 100 mbar for 10 min and the conversion was calculated by integration ofproduct peaks to a quantified internal standard (nitrobenzene).
