  Preparation of chiral organochalcogeno-α-methylbenzyl alcohols via biocatalysis. The role of Daucus carota root

  摘要：

  A series of organochalcogeno acetophenones 3 has been submitted to the action of enzymes from Daucus carota root. Some of the chalcogeno ketones tested afforded the chiral organochalcogeno-alpha-methylbenzyl alcohols 4 in excellent enantiomeric excesses (>99%), under mild and environmentally friendly conditions. The stereoselectivity of the reduction is in accordance with Prelog's rule. Enzymatic kinetic resolution as alternative process was used to obtain the chiral ortho-organochalcogeno-alpha-methylbenzyl alcohols in excellent enantiomeric excess (>99%). (C) 2003 Elsevier Ltd.

  Organoselenium acetophenones oxidation using enzymatic reactions has been developed and chemoselectivity of phenylacetone monooxygenase (PAMO) with selenium-containing ketones has been explored. We discovered that this biocatalyst prefers selenium oxidation, which leads to selenoxide in excellent conversion, over Baeyer–Villiger oxidation.

  已开发出利用酶促反应氧化有机硒苯乙酮的方法，并已探索了苯丙酮单加氧酶（PAMO）与含硒酮的化学选择性。我们发现，这种生物催化剂比硒的氧化更喜欢硒的氧化，而硒的氧化可以使硒氧化物具有出色的转化率。
