Synthetic Route of 31608-22-7. Chemical engineers ensure the efficiency and safety of chemical processes, adapt the chemical make-up of products to meet environmental or economic needs, and apply new technologies to improve existing processes. 31608-22-7, Name is 2-(4-Bromobutoxy)tetrahydro-2H-pyran. In a document type is Article, introducing its new discovery.
1-Bromo-non-4(Z)-ene (II) on reaction with the dianion of propargyl alcohol in liq.NH3 yields the acetylenic alcohol (III) which on LAH reduction gives (2E,7Z)-2,7-dodecadien-1-ol (IV).The bromide (V) obtained from IV when coupled with 1-bromo-4-tetrahydropyranyloxybutane in the presence of Li2CuCl4 affords VI which on hydrolysis gives VII.Acetylation of VII (Py/Ac2O) leads to the title compound (I).
I hope this article can help some friends in scientific research. I am very proud of our efforts over the past few months and hope to 31608-22-7, help many people in the next few years., Reference of 31608-22-7
