Patent ID: 7396849

Claim:
A compound of the formula where R 1 is independently H, alkyl of 1 to 4 carbons, CH 2 OR 2 , or fluoro substituted alkyl of 1 to 4 carbons; R 2 is independently H, alkyl of 1 to 4 carbons, C(O)R 7 , carbocyclic aryl or heterocyclic aryl having 1 to 3 heteroatoms independently selected from N, O and S; R 3 is independently selected from the groups consisting of alkyl of 1 to 4 carbons, alkenyl of 2 to 4 carbons, alkynyl of 2 to 4 carbons, CH 2 OR 2 , CH 2 N(R 2 ) 2 , CH 2 CN, C(O)R 2 , C(O)OR 6 , SO 3 R 6 , SO 2 N(R 2 ) 2 , CH 2 SR 2 , F, Cl, Br, I, fluoro substituted alkyl of 1 to 4 carbons, CN, N 3 , NO 2 , N(R 2 ) 2 , OR 2 , SR 2 ; p is an integer having the values of 0,1, 2, or 3; R 4 and R 5 together with the carbons to which they are attached jointly form a carbocyclic or a heterocyclic ring, the heterocyclic ring having 5 or 6 atoms in the ring and 1 to 3 heteroatoms independently selected from N, O and S; said carbocyclic or heterocyclic ring jointly formed by R4 and R5 being optionally substituted with 1 to 7 R 8 groups; R 6 is independently H, alkyl of 1 to 4 carbons, carbocyclic aryl or heterocyclic aryl having 1 to 3 heteroatoms independently selected from N, O and S; R 7 is H or alkyl of 1 to 4 carbons, and R 8 is independently selected from the groups consisting of alkyl of 1 to 4 carbons, alkenyl of 2 to 4 carbons, alkynyl of 2 to 4 carbons, CH 2 OR 2 , CH 2 N(R 2 ) 2 , CH 2 CN, C(O)R 2 , C(O)OR 6 , SO 3 R 6 , SO 2 N(R 2 ) 2 , CH 2 SR 2 , F, Cl, Br, I, fluoro substituted alkyl of 1 to 4 carbons, CN, N 3 , NO 2 , N(R 2 ) 2 , OR 2 , SR 2 or R 8 is O or S double bonded to one carbon of said carbocyclic or heterocyclic ring.
