Baker's yeast reduction of 4-hetero-2-(2-nitroethyl)cyclohexanones
摘要:
Baker's yeast reduction of 3-(2-nitroethyl)-tetrahydro-4H-pyran-4-one 10 and 3-(2-nitroethyl)-tetrahydro-4H-thiopyran-4-one 11 gave the corresponding optically active cis alcohols with good diastereo- and enantioselectivity. The unreacted optically active ketones were also isolated. (C) 1997 Elsevier Science Ltd.
