supporting information, p. 9934 - 9937 (2021/10/12)
A phosphine-catalyzed cascade (2+3)/(2+4) cyclization reaction of γ-vinyl allenoates with aldimine esters has been developed to provide a series of chromeno[4,3-b]pyrrole derivatives that contain three contiguous stereogenic centers. The method gives a good yield, excellent chemoselectivity and diastereoselectivity under mild conditions.
A novel series of 6-substituted 3-(pyrrolidin-1-ylmethyl)chromen-2-ones as selective monoamine oxidase (MAO) A inhibitors

, p. 177 - 186 (2014/01/23)
A series of 6-substituted 3-(pyrrolidin-1-ylmethyl)chromen-2-ones (coumarins) have been synthesized and their inhibitory activity to human monoamine oxidase A (MAO A) and B (MAO B) determined. Incorporation of a basic amino function in the C3 position together with substitution at the C6 position produced novel coumarin compounds with selectivity for the MAO A subtype. Substitution in the C6 position with small hydrophilic groups such as hydroxy (19, IC50 = 1.46 μM) or amino (18, IC50 = 3.77 μM) gave the most potent and selective compounds for MAO A. These compounds also showed excellent aqueous solubility properties. Compound 18 [6-amino-3- (pyrrolidin-1-ylmethyl)chromen-2-one] administrated in vivo induced in rat brain a neurotransmitter metabolite profile typical of MAO A inhibition: decreased 3,4-dihydroxyphenylacetic acid (DOPAC) and 5-hydroxyindoleacetic acid (5-HIAA) but increased 3-methoxytyramine (3-MT) levels.
