Starting from phosphorylated allenes, a three-steps synthesis of a new class of organic azides with a 1,2-oxaphospholene carbon skeleton has been developed. The series of obtained 4-alkyl-3-azidomethyl-2-ethoxy-2,5-dihydro-5H-1,2-oxaphosphole 2-oxides were utilized in the 1,3-cycloaddition with alkyl 2-[1-(propyn-2-yl)-1H-indol-3-yl]-2-oxoacetates for the synthesis of conjugates, which are potentially active cytostatics.
