Hydroxynitrile lyases (HNL) are one of the key enzymes in cyanogenic plants, catalyzing the final step in the biodegradation pathway of cyanogenic glycosides releasing HCN and the corresponding carbonyl components. We have been able to find some new plant HNL from drupe available in the northern part of the Indian subcontinent. Asymmetric cyanohydrin synthesis from γ,δ-unsaturated aldehydes by applying those new HNL is reported in this communication.
羟腈裂解酶(HNL)是生
氰植物中的关键酶之一,催化生
氰糖苷
生物降解途径的最后一步,释放HCN和相应的羰基成分。我们已能够从印度次大陆北部可获得的核果中找到一些新的植物HNL。本文报道了利用这些新HNL进行的γ,δ-不饱和醛的不对称
