A simple and efficient, Lewis acid catalysed reductive etherification strategy for the stereoselective synthesis of cis-2,6- disubstituted morpholines and 1,4-oxathianes starting from readily available 1,5-diketones has been developed. The strategy is used in the total synthesis of morpholine-based natural products (±)-chelonin A and formal total synthesis of (±)-chelonin C.

Ahead of the PAC: Polycyclic aromatic compounds (PACs) can be easily accessed by the combination of Suzuki-Miyaura cross-coupling and a [Rh 2(OAc)4]-catalyzed carbene reaction using easily available bis(N-tosylhydrazone)s as intermediates (see scheme; Ts=4-toluenesulfonyl). Copyright

From 1b, 1c and 1d no "1,4-oxazines" are available under dehydrating conditions.Only reaction of 1c with PPA at room temperature yields 7, while 1d in dependence of the reaction time with PPA at 100 deg C undergoes cyclisation to the indoles 3b and 3c and
