Photosensitised regioselective [2+2]-cycloaddition of cinnamates and related alkenes.
Chemical Communications, 2017An efficient method for the synthesis of substituted cyclobutanes from cinnamates, chalcones, and styrenes has been developed utilizing a visible-light triplet sensitisation mode. This reaction provides a diverse range of substituted cyclobutanes in high

A decarboxylative Mizoroki-Heck coupling of aryl halides with cinnamic acids has been developed in which the carboxylate group directs the arylation into its β-position before being tracelessly removed through protodecarboxylation.

Phosphine catalysed (5 + 1) annulation of ynone/cinnamates with primary amines.
Chemical Communications, 2017The (5 + 1) annulation of ynone/cinnamates and related substrates with protected primary amines gives rise to isoquinolones, pyrrolidinones and pyrrolopiperazines in good to excellent yields under phosphine catalysis.

The absorption and metabolism of methyl cinnamate
Toxicology, 1977Analysis of the gut contents of rats killed at intervals after dosage with methyl cinnamate or cinnamic acid suggested that both ester and acid were rapidly absorbed; at no time was more than 5% of the dose detected in the lower part of the gut. Not more than 9% of the administered methyl cinnamate was detected in the stomach as cinnamic acid whereas ...

Non-natural cinnamic acid derivatives as substrates of cinnamate 4-hydroxylase
Phytochemistry, 2007Cinnamate 4-hydroxylase (C4H), a monooxygenase in the plant phenylpropanoid pathway, was assayed for its ability to hydroxylate 29 substrate analogues. Nine of the tested analogues with various aromatic side chains, including 3-coumaric acid, were metabolized by C4H.

Chlorogenic acids and other cinnamates – nature, occurrence and dietary burden
, 1999This review defines the range of forms in which cinnamates (p-coumarates, caffeates, ferulates and sinapates) occur in foods and beverages subdividing them into (i) the classic chlorogenic acids and close allies, (ii) other esters, amides and glycosides,

Positive patch test reactions to 2 % cinnamic aldehyde were obtained from 2.8 % of 34 males and 9.1 % of 55 females. The 9.1 % female reactivity may be traceable to perfumed cosmetics. Simultaneous Jasmin allergy is documented us is the occurrence of alpha‐amyl cinnamic aldehyde in synthetic, Jasmin. The relevance of these reactions is discussed.

A novel FeCl3 mediated formal [2+2] cycloaddition/ring opening cascade of o-keto-cinnamates was developed for the synthesis of indenones. The reaction tolerates a broad range of functional groups, including bromide, chloride, amide, acid and ester groups.
