readily react with a variety of dienophiles at temperatures ranging from 0 to 130°C to give derivatives 5–10 of 5-(trialkylsilyloxy)spiro-[2.5]oct-4-ene or the corresponding hydrolysis products 10, 12. Weak dienophiles like cyclohexenone and cyclopentenone give spiro[2.5]octan-5-one derivatives only under BF3 catalysis and with poor yields.
