Introduction of a new synthetic route about Thiomorpholine 1,1-dioxide

The basis of chemical reaction formula synthesis, the synthesis route is composed of some specific reactions and combined according to certain logical thinking. 39093-93-1. We look forward to the emergence of more reaction modes in the future.

Thiomorpholine 1,1-dioxide, A common heterocyclic compound, its traditional synthetic route has been very mature, but the traditional synthetic route has various shortcomings, such as complicated route, low yield, poor purity, etc., below Introduce a new synthetic route., 39093-93-1

Example 39Synthesis of 3-{3-[4-(1-Aminocyclobutyl)phenyl]-5-[3-(1,1-dioxidothiomorpholin-4-yl)phenyl]-3H-imidazo[4,5-b]pyridin-2-yl}pyridin-2-amine trihydrochloride Step 14-(3-Bromophenyl)thiomorpholine 1,1-dioxideA mixture of 1,3-dibromobenzene (242 muL, 2.00 mmol), thiomorpholine 1,1-dioxide (270 mg, 2.00 mmol), Pd2(dba)3 (45.8 mg, 0.0500 mmol), rac-BINAP (96.3 mg, 0.150 mmol) and NaOtBu (231 mg, 2.40 mmol) in toluene was heated at 80¡ã C. for 11 hours under nitrogen. After cooling to room temperature, the mixture was diluted with DCM and filtered through a Celite pad. The combined filtrate and washings were concentrated. The residue was purified by silica gel column chromatography (EtOAc/hexane=90:10–>80:20–>75:25) to afford desired product (281 mg, 48.4percent) as pale yellow solid.400 MHz 1H-NMR (CDCl3) delta: 7.16 (t, J=8.4 Hz, 1H), 7.07-7.02 (m, 2H), 6.85-6.80 (m, 1H), 3.95-3.76 (m, 4H), 3.20-3.02 (m, 4H)., 39093-93-1
