N-Methylative aziridine ring opening: asymmetric synthesis of hygroline, pseudohygroline, and hygrine
摘要:
Asymmetric syntheses of biologically and pharmaceutically important (-)-hygroline, (-)-pseudohygroline, and (-)-hygrine were achieved by a newly developed 'N-methylative aziridine ring opening reactions' of (2S)-methoxycarbonylethylaziridine as a key step.
