Extension of hydrogen borrowing alkylation reactions for the total synthesis of (−)-γ-lycorane

Abstract: The total synthesis of (–)-γ-lycorane (10 steps) was completed from cyclohexenone. This is one of the first examples of hydrogen borrowing C–C bond formation being used as a key step in a total synthesis project.

“…The synthesis of (−)‐γ‐lycorane reported by Donohoe et al [90a] . started by aziridination reaction using 2‐cyclohexen‐1‐one 27 and benzyl (tosyloxy) carbamate 227 , affording azidirine 228 in 64 % yield and 98 : 2 e.r.…”

“…A similar reaction was arranged with a ruthenium catalyst in the same year in Japan (Watanabe et al 1981). Such transformations were later christened as ‘hydrogen-borrowing’ reactions and used widely by others (Hall et al 2022). Another example of Grigg's pioneering rhodium(I)-catalysed reactions under mild conditions was the cyclotrimerization of alkynes to aromatics with the aid of famed hydrogenation catalyst 79 (13).…”

“…Die Bestimmung der Positionen, an denen stereochemische Informationen beibehalten oder eingeführt werden können (Abbildung 2), ermöglichte die Entwicklung einer katalytischen asymmetrischen Variante, bei der ein chiraler Diphosphinligand die faziale Selektivität der Enonreduktion durch Ir−H kontrolliert [17b,19,21] . Donohoe betonte, dass das Testen der Synthesemethoden bei zielgerichteten Syntheseversuchen der Modus Operandi seiner Gruppe ist, [22] wie die Verwendung von “Hydrogen borrowing”‐Alkylierung bei der Totalsynthese von (−)‐γ‐Lycoran zeigt [23] …”
