A chiral C3 triisopropylamine and its silatrane derivatives
摘要:
The first chiral C-3 triisopropylamine has been prepared with the stereogenic centers adjacent to the central nitrogen atom. This triol was converted to two new C-3 4,6,11-trimethylsilatranes. An X-ray structure revealed that the methyl substituents adopt sterically congested pseudoaxial orientations. (C) 1999 Elsevier Science Ltd. All rights reserved.
