Analyzing the synthesis route of 105-21-5

105-21-5, As the paragraph descriping shows that 105-21-5 is playing an increasingly important role.

105-21-5, Gamma-heptalactone is a Tetrahydrofurans compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated

In a dry round bottom flask under argon atmosphere 5 g (27.9 mmol) of (3- aminopropyl)trimethoxysilane (AMMO) was stirred at 50 C. 0.28 ml of 1 M triethylaluminium solution in hexane was slowly added (0.279 mmol, 1 mol%). Afterwards 27.9 mmol of the mono-substituted lactone listed in Table 1 was added and vigorously stirred for 3 hours. (0070) A yellowish and viscous following product from Comparative Example 1 was obtained.
