Diastereoselective synthesis of 2,6-disubstituted 3-hydroxypiperidine, 2-(α-hydroxyalkyl)-3-hydroxypiperidine and 2-(α-hydroxyalkyl)-3-hydroxypyrrolidine derivatives

Kano, Shinzo,Yuasa, Yoko,Mochizuki, Naoki,Shibuya, Shiroshi

, p. 263 - 266 (2007/10/02)

Reduction of 5-substituted 5,8a-trans-oxazolopyridin-8-ones (7a,b), obtained by an application of α-acylamino radical cyclization at the initial stage, with NaBH4 and K-Selectride was found to proceed with complete stereocontrol in all cases.Reduction of 1-substituted 1,8a-trans-oxazolopyridin-8-one (7c) and pyrrolidine analogue (10) with NaBH4 and K-Selectride was also found to proceed with high diastereoselectivity.
