PROCESS FOR THE PREPARATION OF ORGANIC COMPOUNDS WITH MANGANESE CATALYSTS OR THE LIKE
-
Example 11, (2010/01/31)
A process of the present invention produces an organic compound by allowing a compound containing an electron attractive group of following Formula (1):wherein Y is an electron attractive group; and Rb and Rc are each a hydrogen atom or an organic group, where Y, Rb and Rc may respectively be combined with each other to form a ring with an adjacent carbon atom, to react with a compound containing an unsaturated carbon-carbon bond of following Formula (2) or (7):wherein Rd, Re, Rf, Rg, Ri and Rj are each a hydrogen atom or an organic group, where Rd, Re, Rf and Rg may respectively be combined to form a ring with one or two adjacent carbon atoms, and Ri and Rj may be combined to form a ring with adjacent two carbon atoms, in the presence of oxygen and a catalytic compound of a Group 5, 6, 7, 8 or 9 element of the Periodic Table of Elements to yield a compound of following Formula (3) or (8):wherein Z is a hydrogen atom or a hydroxyl group; and Y, Rb, Rc, Rd, Re, Rf, Rg, Ri and Rj have the same meanings as defined above. This process can efficiently produce a compound having an alkyl group or alkenyl group bonded at the alpha position of an electron attractive group, or a derivative thereof, by catalytic radical addition reaction.

We describe a new general method for the synthesis of medium-sized lactones under mild conditions involving β-scission of alkoxy radicals derived from catacondensed lactols as a key step and its application to an efficient new synthesis of a naturally occurring 10-membered lactone, phoracantholide I .
