Some new six-membered aplysinopsin analogues were prepared from 5-dimethyla
minomethylidene-2,4,6(1H,3H,5H)- pyrimidinetriones and indole derivatives.
Also 2-[ [(2,4,6-trioxohexahydropyrimidin-5-ylidene)methyl]amino]-3-dimethy
laminopropenoates were synthesized and employed in the synthesis of fused 2
H-pyran-2-ones. (C) 2001 Elsevier Science Ltd. All rights reserved.
