Carbon Radical Attack on a Pyrimidine Nitrogen. An Unusual Entry into Polycyclic Aminopyrimidones
摘要:
Unprecedented examples of a synthetically useful radical ring closure onto a pyrimidine nitrogen leading to novel, highly functionalized bi- and tricyclic pyrimidone structures are reported. An unexpected hydrogen atom translocation prior to the cyclization step was observed in some cases.

A process for preparing a cyclic polysiloxazane is disclosed. The cyclic polysiloxazane may optionally be converted to an a-alkoxy-ou-amino-functional polysiloxane. The cyclic polysiloxazane or the a-alkoxy-oo-amino-functional polysiloxane, may be used as a capping agent for a silanol-functional polyorganosiloxane in a process to make an amino-functional polyorganosiloxane.
