| Abstract: | Vilsmeier—Haack formylation of methyl lambertianate results in its 16-formyl derivative as the predominant product, which readily enters the intramolecular reaction of photochemical [2+2]-cycloaddition in the absence of a sensitizer.Translated fromIzvestiya Akademii Nauk. Seriya Khimicheskaya, No. 12, pp. 2514–2517, December, 1995. |
