Discovery of C12H23NO3

The synthetic route of 239074-29-4 has been constantly updated, and we look forward to future research findings.

Reference of 239074-29-4,Some common heterocyclic compound, 239074-29-4, name is tert-Butyl (trans-4-(hydroxymethyl)cyclohexyl)carbamate, molecular formula is C12H23NO3, 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.

A suspension of 4-hydroxy-5 -methyl-6-oxo-5,6-dihydro- 1,5 -naphthyridine-3- carbonitrile (100 mg, 0.50 mmol) in THF (10 mL) was stirred at rt and treated with (1,1- dimethylethyl [tralpha/?5-4-(hydroxymethyl)cyclohexyl] carbamate (114 mg, 0.50 mmol), triphenyl phosphine (261 mg, 0.99 mmol) and DIAD (0.20 mL, 0.99 mmol) added dropwise. The resulting pale yellow suspension was stirred at rt for 20 min then heated at 80 0C overnight. The reaction was then heated at 60 0C over the weekend. The reaction was then evaporated to give a yellow gum which was purified by silica chromatography, eluting with MeOH/DCM (0-10%) to give the title compound (0.51 g), containing residual triphenylphosphine oxide. This may be used in the next step without further purification.MS (ES+) m/z 413 [MH+].

The synthetic route of 239074-29-4 has been constantly updated, and we look forward to future research findings.
