专利号:US-10829792-B2 优先权日:2017-03-21 标 题 :Biocatalytic synthesis of strained carbocycles 发明人:CHEN KAI; HUANG XIONGYI; KAN S B JENNIFER 权利人:CALIFORNIA INST OF TECHN 摘要:Provided herein are methods for producing products containing strained carbocycles, such as cyclopropene moieties and/or bicyclobutane moieties. The methods include combining an alkyne and a carbene precursor in the presence of a heme protein, e.g., a cytochrome P450, under conditions sufficient to form the strained carbocycle. Reaction mixtures for producing strained carbocycles are also described, as well as whole-cell catalysts comprising heme proteins and variants thereof for forming cyclopropenes, bicyclobutanes, and related products.
