The present invention provides novel compounds having the general formula: (I) wherein R1, R2, L, and A are as described herein, or a pharmaceutically acceptable salt thereof, compositions including the compounds and methods of using the compounds.
Chiral 1,2,3-triazolium salt-catalyzed asymmetric phase-transfer alkylation of a-cyanosulfones has been developed. This protocol is applicable to a variety of benzylic and allylic halides and cyanosulfones, affording chiral sulfones possessing tetrasubstituted carbons in excellent yields with good-to-high enantioselectivities.
