1.2.1.2. Process for preparation of enhanced South American and South American Monascus and amidas

摘要

The invention refers to a process in which cyclopentanediol reacts with cyclopentanediol (a) or cyclopentanediol reacts with cyclopentanediol, or (d) cyclopentanediol reacts with cyclopentanediol further, so as to prepare cyclopentanediol and corresponding glycol which are rich,(c) To further react with a gain of South and South American cyclophosphamide and a symmetric isomer, or (d) to further react with a counterpart and (E) to obtain (f) a gain of South and South American cyclophosphamide and a symmetric isomer (g) In addition, there is an enhanced southern hemisphere and southern hemisphere epoxidation.
