Abstract: A highly diastereoselective method for the synthesis of syn -β-amino alcohols and enantioenriched anti -β-amino alcohols has been developed involving α-hydroxyl aldehydes and chiral α-phenylaminoxyaldehydes or α-benzoyloxyaldehydes, respectively in Petasis borono-Mannich allylation reactions.

Abstract: The reactions of α,β-unsaturated N -acyliminium ions, generated in situ from 4( S )- O -substitutedhydroxy-5-hydroxy-5-vinyl- N -alkylpyrrolidin-2-ones, with allylsilanes and indoles leading to the formation of spirocyclic heterocycles, are reported.

Abstract: Two new cassane diterpenoids, 14β-hydroxycassa-11(12),13(15)-dien-12,16-olide ( 1 ) and 6′-acetoxypterolobirin B ( 3 ), together with a known analogue, identified as 12α,14β-dihydroxycassa-13(15)-en-12,16-olide ( 2 ), were isolated from the fruits of Pterolobium macropterum . Compound 1 is a cassane diterpenoid with a Δ 11(12) double bond conjugated with an α,β-butenolide-type, whereas compound 3 is a dimeric caged cassane diterpenoid with unique 6/6/6/6/6/5/6/6/6 nonacyclic ring system. The structures of 1 and 3 were characterized by extensive spectroscopic analysis combined with computational ECD analyses. The α-glucosidase inhibitory activity of isolated compounds was evaluated, and compounds 1 and 3 showed significant α-glucosidase inhibitory activity with IC 50 values of 66 and 44 μM.

Abstract: The chemical study of leaf extracts from Uvaria cherrevensis resulted in the identification of 11 new polyoxygenated cyclohexenes, cherrevenols A-K (1-11), and a new seco-cyclohexene derivative, cherrevenol L (12). Nine known compounds (13-21) were also isolated. Three of the isolated compounds are chlorinated polyoxygenated cyclohexenes. The structures of these compounds were determined using spectroscopic methods and, in some cases (compounds 2, 6, 8, and 10), single-crystal X-ray crystallographic structural analysis or chemical correlation (compounds 6 and 7). Compounds 6 and 7 were both isolated as scalemic mixtures (ee 23-24%).
