Abstract
This application discloses a kind of methods for synthesizing 1,2- dimethylene cyclobutane chipal compounds to synthesize 1,2- dimethylene cyclobutane chipal compounds by connection enamine compound in the presence of rhodium complex.This method can under mild reaction conditions, the synthesis 1 of high efficiency, high enantioselectivity and highly-solid selectively, 2- dimethylene cyclobutane chipal compounds.
Description
Technical field
This application involves a kind of methods for synthesizing 1,2- dimethylene cyclobutane chipal compounds, belong to natural products and medicine
Object field.
Background technique
Cyclobutane derivative compound has critical role in many natural products and drug molecule.And ring fourth is synthesized at present
The method of alkane mainly passes through alkene, alkynes, connection alkene and other unsaturated systems and synthesizes cyclobutane by [2+2] cycloaddition.Closely
Nian Lai has synthesized the method for cyclobutane making alkene or connection alkene that [2+2] cycloaddition occur with other unsaturated systems by heating
Largely studied, but such reaction has that selectivity is bad, reaction temperature is high (typically larger than 200 DEG C), when reaction
Between long (typically larger than 72h) the shortcomings that.
As the method for [2+2] cycloaddition synthesis cyclobutane makes progress in photocatalysis field, [the 2+ about metal catalytic
2] cycloaddition synthesis cyclobutane method gradually increase, wherein report about gold [Angew.Chem.Int.Ed.2009,48,
