Thesynthesisof2-amino-5,5-dimethyl-3-cyano-4,5-dihydro-7H-furo[2,3-c]pyrananditspyrroleanalog was accomplished on the basis of 2,2-dimethyltetrahydro-4-pyranone. Their reaction with maleic anhydride, which leads to the formation of 3-amino-4-cyano-6,

Publikováno v: Chemistry of Heterocyclic Compounds. 26:1170-1172

Using o-iodobenzoic acid we synthesized 5-hydroxy-2,2-dimethyltetrahydrothiopyran-4-one. From the latter we synthesized 2-amino-5,5-dimethyl-3-cyano-4,5-dihydro-7H-furo[2,3-c]thiopyran; this is a starting material for the preparation of furo[2,3-d]py

The photochemical cycloaddition of 2-acetyl-3,4,4-trimethyl-2-buten-4-olide to 1-heptyne and 1-chloro-2-propyne was carried out. The reaction gives isomeric cycloadducts of the “head to head” and “head to tail” types. The influence of solvent
