The invention provides antitumour compounds of formula (I), wherein R1 is an aromatic substituent; R2 is hydrogen or a substituent when the dotted line is absent, or R2 is absent when the dotted line represents a bond to give a double bond between the nitrogen which bears R2 and the carbon which bears R3; R3 is an oxo group ═O when the dotted line is absent or is a substituent when the dotted line represents a bond to give a double bond between the nitrogen bearing R2 and the carbon bearing R3; R4 is hydrogen or a substituent; and pharmaceutically acceptable salts thereof.

Two alternative synthetic routes have been developed for the preparation of variolin B and deoxyvariolin B. The strategy is based on the preparation of the core tricyclic ring common to all variolins, pyrido[3′,2′ :4,5]pyrrolo[1,2-c]pyrimidine, followed b

The total synthesis of variolin B from 4-methoxy-7-azaindole is described. The preparation of the protected amino derivative 10 and a coupling reaction of the iodo derivative 12 with 2-acetylamino-4-trimethylstannylpyrimidine are the key steps of the sequ
