Several estrogens were mono-formylated using a mixture of paraformaldehyde. MgCl2, and Et3N in refluxing THF. In all cases, the 2-isomer was formed as the major product with high regioselectivity compared to the 4-isomer. Excellent to high yields were obtained in all examples except one. The method was applied for an efficient synthesis of the anti-cancer agent 2-methoxyestradiol. (C) 2011 Elsevier Ltd. All rights reserved.
