(2endo)-2-Chloro-1,4,4-trimethyl-8-oxabicyclo[3.2.1]oct-6-en-3-one (2) is synthesized via [4+3] cycloaddition of an oxyallyl intermediate generated from 1,3-dichloro-3-methylbutan-2-one with lithium perchlorate / diethylether / triethylamine.[...]

We report the synthesis of (2endo)-2-Chloro-4,4-dimethyl-8-oxabicyclo[3.2.1]oct-6-en-3-one (2) and (2endo)-2-chloro-1,4,4-trimethyl-8-oxabicyclo[3.2.1]oct-6-en-3-one (3) via [4+3] cycloaddition of an oxyallyl intermediate generated from 1,3-dichloro-...

5-Methylfurfurylamine was prepared from commercially available 5-methylfurfural via the oxime, followed by LiAlH4 reduction [1].[...]

A mixture of N-furfuryl-p-toluenesulfonamide (1) (2.51 g, 10 mmol) [1] and pentachloroacetone [2] (3.23 g, 14 mmol) was cooled in an ice bath.[...]

A mixture of 1 [1] (2.65 g, 10 mmol) and pentachloroacetone [2] (3.23 g, 14 mmol) was cooled in an ice bath.[...]

Zinc powder (10.6 g, 160 mmol) was given to an ice-cold solution of methanol (40 mL) saturated with ammonium chloride.[...]

There is considerable interest in the synthesis of new materials with large second-order optical non-linearity because of their potential applications in optical data storage, telecommunications and optical signals processing [1,2,3,4].[...]

The combination of microwave irradiation and solvent-free conditions leads to enhanced reaction rates, higher yields of pure products, easier work-up and several advantages of the eco-friendly approach in the framework of green-chemistry [1,2].[...]

As part of our ongoing research program on bicyclic heteroaromatics chemistry [1,2,3,4] we synthesised the title compounds with the goal of performing structure-activity relationship studies.[...]
