A novel isoxazole-based scaold has been identi®ed for the generation of combinatorial libraries using solid-phase methods. This scaold has been utilized to aord high value synthetic intermediates through Baylis±Hillman reaction, Wittig reaction, nitroaldol condensation, and imine and oxime formation

✦ Synopsis
The steroid 3, with three independently-addressable, rigidly-positioned functional groups, has been synthesized in an efficient, multi-gram sequence from inexpensive cholic acid 1. Compound 3 should prove valuable as a starting point for combinatorial libraries with preorganised, co-directed arrays of substituents.
