Abstract

Chromanones are widely distributed in many natural products 1 and have many biologic activity such as anti-HIV-1 activity. 2 The construction of these compounds have attracted much attention in the synthetic community over the last few decades. Previously, the conventional methods for the building of chromanones mainly included: (a) oxo-Michael addition of o-tiglolylphenol, 3 (b) cyclization of the corresponding chromene with paraldehyde in the presence of ...
