competitive, reversibleinhibitor that binds the BTK protein in a DFG-in confirmation designed to sequester Tyr-551, an important phosphorylation site on BTK, into an inactive conformation with excellent affinity. Preclinical studies demonstrated BIB091 to be a high potency molecule with good drug-like properties and a safety/tolerability profile suitable for clinical development as a highly selective, reversible

New Horner-Emmons reagents, ethyl (diarylphosphono)acetates 1, were prepared from triethyl phosphonoacetate, PCl(5), and the corresponding phenols. The reaction of 1 with several kinds of aldehydes in the presence of Triton B or NaH in THF solvent revealed that these reagents are useful for the synthesis of Z-unsaturated esters. Among the reagents examined, ethyl(di-o-tolylphosphono)-, [bis(o-ethylphenyl)phosphono]-

The utility of the weak base potassium tert-butoxide has been successfully demonstrated in the synthesis of ß-lactams and 3, 4-dihydropyridin-2-ones starting from esters and imines.
<i>Z</i>-Selective Horner−Wadsworth−Emmons Reaction of α-Substituted Ethyl (Diarylphosphono)acetates with Aldehydes<sup>1</sup>

New Horner-Wadsworth-Emmons reagents, ethyl 2-(diarylphosphono)propionates (2), ethyl 2-(diarylphosphono)hexanoates (3), and ethyl 2-(diarylphosphono)-3-methylbutanoates (4) were prepared by alkylation of ethyl (diarylphosphono)acetates. The reaction of 2-4 with various types of aldehydes gave Z-alpha,beta-dialkyl-alpha,beta-unsaturated esters highly selectively. Remarkable temperature-dependent selectivity was observed in the reaction of (PhO)(2)P(O)CHBuCO2Et with octyl aldehyde.
