Abstract
Formal total syntheses of (–)-indolizidines 205A, 207A, and 235B have been accomplished using Evans aldol, Horner–Wadsworth–Emmons olefination and reductive cyclization as key reactions.
Key words
alkaloid - indolizidine - Evans aldol - Horner–Wadsworth–Emmons olefination - reductive aminationSupporting Information
