Some unusual transformations of a highly reactive α-bromocaranone

The facile synthesis of a highly reactive α-bromocaranone from (+)-carene is reported. This intermediate was found to generate diverse chiral building blocks through radical or carbocation mediated cyclopropyl fragmentation reactions in moderate to excellent yields. Furthermore, the formation of an unexpected carvone derivative prompted several control studies that provided mechanistic insight into an unusual transformation. This study not only demonstrates the synthesis of a variety of chiral building blocks but provides insight into the reactivity of keto-halo-cyclopropanes in general.

IMPROVEMENTS IN OR RELATING TO ORGANIC COMPOUNDS

Disclosed is a compound represented by formula (I). The half-doted double lines each represent a carbon-carbon single bond or a carbon-carbon double bond. The six-membered ring comprises exactly one endocyclic carbon-carbon double bond or exactly two endocyclic carbon-carbon double bonds. When the six-membered ring comprises exactly two endocyclic carbon-carbon double bonds, the endocyclic carbon-carbon double bonds are either in 1,3-relationship or in 1,4-relationship. R is selected from the group consisting of iso-propyl, iso-butyl, sec-butyl and tert-butyl.

Sodium metaperiodate oxidation of isocarvacrol 8, a monoterpene phenol has been found to give hydrothymoquinone 13, a natural product and a ring cleavage product 7-oxo-5-isopropyloct-3-en-2,5-olide 14.

Preparation of diphenolics

A process for the production of diphenolic compounds having a divalent bridge. A first disubstituted phenol is reacted with an aldehyde in the presence of a secondary amine and excess alcohol to form an ether intermediate. The ether intermediate is reacted with a phenol having an open ortho or para position to form a diphenolic.
