  Methods are provided for carrying out carbene transfer transformations such as olefin cyclopropanation reactions, carbene heteroatom-H insertion reactions (heteroatom = N, S, Si), sigmatropic rearrangement reactions, and aldehyde olefination reactions with high efficiency and selectivity by using a novel class of myoglobin-based biocatalysts. These methods are useful for the synthesis of a variety of organic compounds which contain one or more new carbon-carbon or carbon-heteroatom (N, S, or Si) bond. The methods can be applied for conducting these transformations in vitro (i.e., using the biocatalyst in isolated form) and in vivo (i.e., using the biocatalyst in a whole cell system).

  提供了一种方法来进行碳烯转移反应，如烯烃环丙烷化反应，碳烯杂原子-H插入反应（杂原子= N，S，Si），σ迁移重排反应和醛烯化反应，通过使用一种新型的基于肌红蛋白的生物催化剂，可以高效和选择性地进行。这些方法对于合成含有一个或多个新碳-碳或碳-杂原子（N，S或Si）键的各种有机化合物非常有用。这些方法可以应用于体外（即使用分离形式的生物催化剂）和体内（即在整个细胞系统中使用生物催化剂）进行这些转化。
