With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.29943-42-8,Dihydro-2H-pyran-4(3H)-one,as a common compound, the synthetic route is as follows.
(r) 2-alpha, 3-alpha-dihydroxy-4beta-[2-(tetrahydropyran-4-yl)-ethylamino-9-adenyl]-cyclopentane-1beta-N-ethylcarboxamide; the starting 2-(tetrahydro-pyran-4-yl)-ethylamine can be prepared from tetrahydropyran-4-one e.g. by Wittig condensation with diethyl cyanomethyl phosphonate followed by hydrogenation and reduction with lithium aluminum hydride;
29943-42-8, 29943-42-8 Dihydro-2H-pyran-4(3H)-one 121599, aTetrahydropyrans compound, is more and more widely used in various.
