Sleep macro- and micro-structure in autoimmune encephalitis: single case report from the subacute phase of the disease to the follow-up.

Sleep disorders are frequently described in autoimmune encephalitis (AE); however, data on sleep texture are fragmentary. We analyzed the polysomnography of a woman affected by AE, and we performed cyclic alternating pattern (CAP) scoring during the subacute phase of the disease and at follow-up. The first polysomnography showed deviations both at macro and microstructure levels, with a marked reduction of CAP rate compare to healthy sleepers (20.

A practical synthetic route to functionalized THBCs and oxygenated analogues via intramolecular Friedel-Crafts reactions.

A practical catalytic approach to the synthesis of 4-substituted 1,2,3,4-tetrahydro-beta-carbolines (THBCs, 1) and 1,2,3,9-tetrahydropyrano[3,4-b]indoles (2) via InBr3-catalyzed intramolecular Friedel-Crafts (F-C) cyclization is described. The use of cross-metathesis reaction represents a direct route to the cyclization precursors and the use of InBr3 (5 mol%) allowed polycyclic indole compounds to be isolated in high yields under mild reaction conditions (rt, DCM, minutes). Finally, efforts toward the development of a stereocontrolled version of the present cyclization are presented, highlighting [salenAlCl] and bimetallic [(salenAlCl)2-InBr3] system as promising chiral Lewis acids (ee up to 60%).
