Ortho-TMS Benzaldehyde: An Effective Linchpin for Type II Anion Relay Chemistry (ARC)

摘要

Ortho-TMS benzaldehyde, an effective bifunctional linchpin for Type II Anion Relay Chemistry (ARC), permits efficient multi-component union of a variety of nucleophiles and electrophiles, including the first example of a Pd-mediated ARC Type II process. To demonstrate the utility of the Type II ARC protocol, a “proof of concept” synthetic sequence was designed and implemented for construction of a focused library of “natural product-like” compounds.
