| Description | Preaparation of substituted propargylvinylethers and their rearrangement to substituted allenylaldehydes is described. These react with protected 4-methoxybenzaldehyde hydrazone. The deprotection is carried out in situ. Prepared nonsymetrical azines in the presence of phenylisocyanate afford in mixed inter-intramolecular criss-cross cycloaddition new till now unknown fused heterocyclic compounds. |
