Synthesis of Functionalized Chromans by PnBu3-Catalyzed Reactions of Salicylaldimines and Salicylaldehydes with Allenic Ester
摘要:
P(n)Bu3-catalyzed cyclization reactions of salicylaldimines and salicylaldehydes with ethyl 2,3-butadienoate gave the corresponding functionalized chromans in moderate to good yields in THF under mild conditions. The new reaction provides a new method for the synthesis of biologically active chroman products.
