We developed a visible-light driven oxo-acyloxylation of aryl alkenes with carboxylic acids and molecular oxygen. A metal-free photoredox system, consisting of an acridinium photocatalyst, an organic base, and molecular sieve (MS) 4 ?, promotes chemoselective aerobic photooxidation of aryl alkenes. This approach may provide a green, practical, and metal-free protocol for a wide range of α-acyloxy ketones.

The present invention provides non-peptide compounds of formula (I) wherein: X is -(C1-C8)allcyl-, aryl or -aryl(C1-C8)alkyl-; Y is -(C1-C8)alkyl- or absent; W is heteroaryl, (C3-C7)carbocycle or aryl, wherein any heteroaryl, (C3-C7)carbocycle or, aryl of W is optionally substituted with one or more (e.g. 1, 2, 3, 4 or 5) Z1 groups; R1 is (C1-C8)alkyl, (C2-C8)alkenyl, (C2-C8)alkynyl or aryl, wherein aryl is optionally substituted with one or more (e.g. 1, 2, 3, 4 or 5) groups selected from (C1-C8)alkyl, (C2-C8)alkenyl, (C2-C8)alkynyl, (C3-C7)carbocycle, halo(C1-C3)alkyl, -CN, NO2, halogen, -ORa, -SRa, -S(O)2NRbRc, -NRbRc, -NRaCORd, -C(O)Ra, -C(O)ORa, and -C(O)NRbRc; R2 is (C1-C8)alkyl, (C2-C8)alkenyl, (C2-C8)Jalkynyl or aryl, wherein aryl is optionally substituted with one or more (e.g. 1, 2, 3, 4 or 5) groups selected from (C1-C8)alkyl, (C2-C8)alkenyl, (C2-C8)alkynyl, (C3-C7)carbocycle, halo(C1-C3)alkyl, -CN, NO2, halogen, -ORe, -SRe, -S(O)2NRfRg, -NRfRg -NReCORh, -C(O)Re, -C(O)ORe and -C(O)NRfRg; I that mimic the streptococcal; SspB Adherence Region (BAR) and function as inhibitors of P. gingivalis adherence to streptococci. The invention also provides methods of making and using the inhibitors.
