This article highlights my recent studies on development of optically active hypervalent iodine (III) reagents which have a chiral side chain derived from lactic acid. The lactate chiral side chain may nucleophilically interact with the iodine ato...
The ring opening of alkylidenecyclopropanone acetal under acidic conditions produces the 1-alkylidene-2-oxyallyl cation as an intermediate, which reacts with furan to give the [3+2] and [4+3] cycloadducts as well as an electrophilic substitution p...

Ring opening reactions of 2-cyclohexylidene-3,3-dimethylcyclopropanone acetal (1) are readily induced by treatment of hydrogen chloride in various solvents. Bond cleavage takes place at the C1-C2 or C2-C3 bond, and the ratio of C1-C2/C2-C3 cleavag...
