Abstract:

Under alkali treatment, Hemslecin A becomes its isomer Hemslecin C by acetyl migration. In this paper, the chemical structure of Hemslecin C was eluci
dated unambiguously by NMR spectroscopy, including 2D 1H-1H COSY, HMQC and HMBC. The 13C and 1H chemical shifts of the compound were ass
igned.

Key words: NMR, assignments, HMQC, Hemsleya amabilis,  Hemslecin C
