摘要
The direct three-component aza-Diels–Alder reaction was conducted with lipase as a catalyst for the first time. Under the optimized conditions, the aza-Diels–Alder reaction catalyzed by lipase from Candida sp. 99–125 provided the products in moderate to excellent yields. Meanwhile, the endo / exo ratio reached up to 88:12.
