Abstract
A novel protocol has been developed for the preparation of highly functionalized 2-azabicyclo[3.3.1]nonane (morphan) derivatives by the interesting three-component cascade reaction of 3-formylchromones, 2-naphthol, and heterocyclic ketal aminals (HKAs) in the ionic liquid [BMIM]PF6 promoted by the organic base Et3N. A complex cascade reaction is required, which includes a 1,2-addition, two Michael reactions, two tautomerizations, and an N-alkylation accompanied by a ring-opening reaction and involving the cleavage of one C-O bond and the formation of four bonds (one C-N bond, one C-O bond, and two C-C bonds). As a result, functionalized morphans (5 and 6) bearing naphthalene-structured skeletons were prepared by simple heating of a mixture of 3-formylchromones, 2-naphthols, and HKAs in the environmentally friendly ionic liquid [BMIM]PF6. This protocol can be used in the synthesis of various morphans and is suitable for combinatorial and parallel syntheses of natural-like morphan derivatives. This approach has several advantages such as the use of an environmentally friendly solvent, simple and practical operation (multicomponent one-pot reaction), and satisfactory yields (65-88%).

Abstract
![]()
The
enantioselective total synthesis of madangamine E has been
completed in 30 steps, enabled by a new catalytic and highly enantioselective
desymmetrizing intramolecular Michael addition reaction of a prochiral
ketone to a tethered β,β′-disubstituted
nitroolefin. This key carbon–carbon bond forming reaction efficiently
constructed a chiral bicyclic core in near-perfect enantio- and diastereo-selectivity,
concurrently established three stereogenic centers, including a quaternary
carbon, and proved highly scalable. Furthermore, the pathway and origins
of enantioselectivity in this catalytic cyclization were probed using
density functional theory (DFT) calculations, which revealed the crucial
substrate/catalyst interactions in the enantio-determining step. Following
construction of the bicyclic core, the total synthesis of madangamine
E could be completed, with key steps including a mild one-pot oxidative
lactamization of an amino alcohol, a two-step Z-selective
olefination of a sterically hindered ketone, and ring-closing metatheses
to install the two macrocyclic rings.

Abstract
A regioselective method for the synthesis of 1-(hydroxymethyl)-2,3-dihydropyrrolo[1,2-a]quinazolin-5(1H)-ones - close structural analogs of naturally occurring vasicinone alkaloids - is described. The procedure is based on PIFA-initiated oxidative 5-exo-trig cyclization of 2-(3-butenyl)quinazolin-4(3Н)-ones, in turn prepared by thermal cyclocondensation of the corresponding 2-(pent-4-enamido)benzamides. The products obtained have a good natural product likeness (NPL) score and therefore can be useful for the design of natural product-like compound libraries.
