simple, efficient and general method has been developed for the synthesis of 1-aminoalkyl phosphonates through a one-pot reaction of aldehydes with amines in the presence of acidic aluminaundersolvent-free conditions using microwave irradiation. It was also found that acidic aluminasupportedammonium formate undersolvent-free conditions is capable of the synthesis of 1-aminophosphonates from aldehydes

A series of new amino phosphonicacid derivatives of vinblastine (1, VLB) has been synthesized and tested in vitro and in vivo for antitumor activity. The compounds were obtained from O4-deacetyl-VLB azide. All of the new products studied were capable of inhibiting tubulin polymerization in vitro. The most potent antitumor compounds bore an alkyl substituent on the phosphonate. In these compounds,
