Scope and Limitations of Optical Pure Hydantoins as Chiral Auxiliaries in Asymmetric Mannich Reactions
《Chemical Research in Chinese Universities》2016年第2期219-225,共7页CHEN Feng LU Cuifen NIE Junqi CHEN Zuxing YANG Guichun 
Supported by the National Natural Science Foundation of China（No.21342002）.
The Mannich reaction of various 5-substituted and N-acyl substituted chiral hydantoins with a series of aldimines smoothly occurred with full stereochemical control. These Mannich adducts have been cleaved by alcoholy...

Simple Reduction of Hydantoins with Sodium Borohydride
《International Journal of Organic Chemistry》2014年第5期286-291,共6页Jun-Ichi Yamaguchi Emiko Shibuta Yoshie Oishi 
The reduction of various hydantoins with sodium borohydride gave the corresponding 4-hydroxy- 2-imidazolidinones in high yields. In contrast, reduction employing a boron trifluoride etherate-sodium borohydride system ...
