| Resumo | |
Chiral chlorohydrins are used as intermediates in the synthesis of various compounds with biological activities. This paper reports the synthesis of alpha-chloroketones 2a-c with oxone (R) and NH4Cl at reflux via 30 min of exposure to microwave irradiation and conventional heating, in situ, followed by reduction with whole cells of marine-derived fungi (Penicillium citrinum CBMAI 1186, Mucor racemosus CBMAI 847, Aspergillus sydowii CBMAI 935, Penicillium raistrickii CBMAI 931, and Penicillium oxalicum CBMAI 1185), yielding the respective chlorohydrins 3a-c with good conversion (32-97%) and enantioselectivities (60-94%). This is the first study involving the synthesis of alpha-chlorophenones in situ followed by biocatalytic reduction from whole cells of marine-derived fungi to obtain enantio-enriched chlorohydrins 3a-c.
