Abstract:
The present technology relates generally cyclobutane boronates, including methods of preparation by exposing a mixture of a compound of Formula I in a solvent and a catalytic amount of a visible light sensitizer to provide a compound of Formula II, stereoisomers thereof, and/or salts of any of the foregoing. The cyclobutane boronate compounds are useful intermediates in the preparation of pharmaceutically active compounds as well as other other useful compounds.

Claim (Index 1):
A method for making cyclobutane boronates comprising exposing a mixture of a compound of Formula I in a solvent and a catalytic amount of a visible light photosensitizer to provide a compound of Formula II, stereoisomers thereof, and/or salts of any of the foregoing, wherein\n X is O, NR 6 , S, C 1 -C 12  alkylene or a C 1 -C 12  heteroalkylene wherein the heteroatom is selected from O, NR 6 , or S; \n Y 1  and Y 2  are independently selected from O, CR 7 2 , or NR 7 ; or Y 1  and Y 2 are both F and the boron atom forms a fluoride salt with a third fluorine atom and an alkali metal cation; \n Z 1  and Z 2  are independently selected from a substituted or unsubstituted H or a substituted or unsubstituted C 1 - 12  alkyl, C 2 - 12  alkenyl, aryl, aralkyl, heteroaryl, or heteroaralkyl group, or \n Z 1  and Z 2  together form Z, wherein Z is selected from a substituted or unsubstituted C 2 -C 12  alkylene, C 2 -C 12  heteroalkylene, or phenylene group; \n R 1  is a substituted or unsubstituted alkenyl, alkynyl, aryl, or heteroaryl group; \n R 2 , R 3 , R 4  and R 5  are each independently H or a substituted or unsubstituted alkyl group; \n R 6  and R 7  at each occurrence are independently selected from H, a substituted or unsubstituted aryl or aralkyl group, or a R 8 SO 2 , R 9 OC(O), or R 10 C(O) group; and \n R 8 , R 9  and R 10  at each occurrence are independently selected from a substituted or unsubstituted alkyl, aryl, or aralkyl group.
