37 - 033Synthesis and Conformational Analysis of 2,6-Dimethyl-1,5-diaza-cis-decalins. — The diastereoselective syntheses of the title compounds(IV) and (VIII) with the dimethyl groups syn or anti to the angular hydrogensare performed starting from cis-1,5-diaza-decalin derivatives (I) and (V). Byreversal of the hydrogenation/deprotection steps, starting from dimethylenederivative (VI), both target diastereomers are available as major products. —(KOZLOWSKI, MARISA C.; XU, ZHENRONG; SANTOS, A.
