Abstract: Poly(vinyl ketones) (PVKs) have received considerable attention over the past few decades due to their unique photochemistry and photodegradation properties under ultraviolet light. Many PVKs rapidly undergo photodegradation under UV light. The side-chain carbonyl moieties… read more here.

Abstract: The development of electron-demand disfavored [4 + 2] cycloaddition of two electron-deficient reacting partners poses a considerable challenge. An enantioselective aza-[4 + 2] cycloaddition of electron-deficient N-sulfonyl-1-aza-1,3-dienes is possible with vinyl ketones via phosphine catalysis,… read more here.

DOI: 10.1021/acscatal.7b00030
Abstract: A chiral amide-phosphine bifunctional catalyst was developed and successfully applied to the asymmetric intermolecular cross-vinylogous Rauhut–Currier of alkyl vinyl ketones with para-quinone methides, offering excellent regioselectivity and stereoselectivity (up to >99% enantiomeric excess (ee)). This… read more here.
