Regio- and stereocontrolled preparation of alpha-substituted phosphonocrotonate derivatives
No full textUnder suitable reaction conditions, monoalkylation of triethyl phosphonocrotonate 11 could be efficiently accomplished, leading to the preparation of a-substituted phosphonates 15. The reaction is totally regioselective and completely (E)-selective. The novel phosphonocrotonate 19 underwent smooth Horner-Emmons condensation, producing a key-precursor for the synthesis of the middle core of the manzamine alkaloids. (C) 2002 Elsevier Science Ltd.
