  Stereochemistry of the reversible cyclization of .omega.-formylalkyl radicals

  摘要：

  The reactions of 6-bromo-4-(1',1'-dimethylethyl)hexanal (4), 5-bromo-3-(1',1'-dimethylethyl)pentanal (11), and 5-bromo-4-(1',1'-dimethylethyl)pentanal (17) with tributylstannane have been investigated in detail. The major products are the debrominated aldehydes and cycloalkanols which arise from the cyclization of the intermediate omega-formylalkyl radicals. The stersochemical outcome of the cyclization of these radicals is dependent on the stannane concentration. At high concentrations of stannane the cyclization is essentially irreversible with the cycloalkoxy radicals being trapped before beta-scission can occur. Under these conditions the relative amount of cis and trans cycloalkanols formed are equal to the ratio of the rate constants for the two modes of cyclization; both 4 and 17 show a small preference for trans cyclization, but 11 gives equal amounts of the two diastereomers. When the stannane concentration is lowered, the lifetime of the cycloalkoxy radicals increases allowing beta-scission to occur. Thus, the cis and trans cycloalkoxy radicals approach a thermodynamic equilibrium which is reflected in the relative yields of the cis and trans cycloalkanols.

• Redox‐Neutral Multicatalytic Cerium Photoredox‐Enabled Cleavage of O−H Bearing Substrates
  作者：Avery O. Morris、Louis Barriault

  DOI：10.1002/chem.202400642

  日期：——

  An approach toward general β C−C bond scission reactions of carboxylic acids and hemiacetals is presented. The present work demonstrates the power of a multicatalytic cerium-based photoredox platform to enable direct hydrodecarboxylation of carboxylic acids as well as redox-neutral ring cleavage of lactol derivatives.
