Abstract
Process for the preparation of endoethenocodide derivatives of general formula I: ** (See formula) ** wherein R1 is hydrogen, lower alkyl or lower alkanoyl; R 2 is hydrogen, cyano, propargyl, lower alkyl, low aralkyl, low alkenyl, cycloalkanecarbonyl, or low cycloalkylmethyl; (see formula) is pyrrolidinyl, piperidino, morpholino or di (lower alkyl) amino; and R is cyano, formyl, carbamyl, mono (lower alkyl) carbamyl, di (lower alkyl) carbamyl, lower alkanoyl, low cycloalkanoyl, benzoyl, low carboalkoxy, carbo (phenyl lower alkyl) oxy or (see formula), wherein R3 and R4 are the same or different and are each hydrogen, lower alkyl, phenyl, low cycloalkyl, or low aralkyl and R5 is hydrogen or low alkanoyl, characterized in that a dienamine of formula is reacted General II: ** (See formula) ** where R1, R2 and (see formula) have the equivalences indicated above, with a dienophyll of general formula III: CH2=CH-A III wherein A is cyano, formyl, carbamyl, mono (lower alkyl) carbamyl, di (lower alkyl) carbamyl, lower alkanoyl, low cycloalkanoyl, benzoyl, low carboalkoxy, or carbo (phenyl lower alkyl) oxy to form a compound of formula General IV: ** (See formula) ** where A, R1, R2 and (see formula) have the indicated values.
