Organolithium-induced synthesis of acyclic unsaturated amino alcohols from epoxides of dihydropyrroles and tetrahydropyridines
摘要:
The alkylative double ring-opening of Bus-protected 2,5-dihydropyrrole epoxides 13 and 29 with organolithiums to give 3-substituted 1-aminobut-3-en-2-ols 13-19 and 30-32 are described. Bus-protected tetrahydropyridine epoxide 38 reacts with organolithiums to give 4-substituted 1-aminobut-4-en-3-ols 39 and tetrahydropyridinol 40. (C) 2003 Elsevier Ltd. All rights reserved.

unactivated monosubstituted, 1,1-disubstituted, and trisubstituted alkenes is disclosed. The reaction is notable in that it converts highly substituted alkenes, aryl bromides, and diboron reagents to products that contain a quaternary carbon and a synthetically versatile carbon-boron bond with control of stereoselectivity and regioselectivity. In addition, the method is demonstrated to be useful for the
