Abstract: Herein, we report the substitution reactions of para‐hydroxybenzyl alcohols catalyzed by the phosphazene base t‐Bu‐P2. This system is compatible with substrates bearing various functionalities, including alkyl, methoxy, thiophenyl, halogen, ester, and amide moieties. Thiols, 1,3‐dicarbonyl… read more here.

Abstract: A new efficient formal [2 + 3] cyclization of p-hydroxybenzyl alcohols with difluoroenoxysilanes has been established. This convenient one-pot sequential procedure enables the divergent construction of highly functionalized gem-difluorinated oxa-spirocyclohexadienones under mild conditions. As opposed… read more here.

DOI: 10.1177/09540083221113974
Abstract: Two series of bifunctional benzoxazines were synthesized from o- and p-hydroxybenzyl alcohols (oHBA and pHBA), three aliphatic diamines containing ether linkage (Jeffamines D230 and D400 and 4,7,10-trioxa-1,13-tridecanediamine (TTDDA)), and paraformaldehyde. The chemical structures of the… read more here.
