The present invention relates to 16-membered macrocyclic compounds. In one aspect of the present invention, compounds of the formula
are provided wherein:
R1, R2, R3, and R5 are each independently hydrogen, C1-C10 alkyl, C2-C10 alkenyl, C2-C10 alkynyl, aryl or alkylaryl;
R4 is hydrogen, halogen, C1-C10 alkyl, C1-C10 hydroxyalkyl, C1-C10 haloalkyl, aryl, —C(═O)R6, —C(═O)OR6, —NR6R7 where R6 and R7 are each independently hydrogen, C1-C10 aliphatic, aryl or alkylaryl;
W is O, NR8 where R8 is hydrogen, C1-C10 alkyl, C2-C10 alkenyl, C2-C10 alkynyl, aryl or alkylaryl;
X is O, CH2 or a carbon-carbon double bond;
Y is absent or a C1-C10 alkyl, C2-C10 alkenyl, or C2-C10 alkynyl; and
Ar is aryl; provided that 10,11-dehydroepothilone C is excluded.
