Short and stereoselective synthesis of polysubstituted cyclohexanones
摘要:
Two equivalents of dimethyl 1,3-acetonedicarboxylate reacted with alpha,beta-unsaturated aldehydes to form novel polysubstituted cyclohexanones 2 in an efficient one-step procedure. The reactions proceeded at room temperature in the presence of catalytic amount of sodium methoxide, affording the products in high yields in a remarkably stereoselective manner. The products are of possible biological interest. (C) 2004 Elsevier Ltd. All rights reserved.
