Diastereoselective synthesis of 2-oxiranyl and 2-aziridinyl thiazoles
摘要:
2-Chloroalkylthiazolyllithiums, prepared by deprotonating the 2-chloroalkylthiazoles with n-BuLi at -78degreesC in THF, add to ketones or imines affording in 'one-pot' oxiranes and aziridines in a Z stereoselective manner. (C) 2003 Elsevier Science Ltd. All rights reserved.
