标 题 :Synthesis of non-symmetrical sulfamides using burgess-type reagents
发明人：NICOLAOU KYRIACOS C; LONGBOTTOM DEBORAH; SNYDER SCOTT A; HUANG XIANHAI
权利人:SCRIPPS RESEARCH INST
摘要:A practical and high-yielding method for the efficient, one-step synthesis of diverse classes of N,N′-differentiated sulfamides employs a wide range of amino alcohols and simple amines using Burgess-type reagents. This methodology extends the application and availability of sulfamides within the fields of chemical biology, medicinal chemistry, asymmetric synthesis, and supramolecular chemistry.

标 题 :Spiroketals useful as intermediates in the synthesis of milbemycin and avermectin macrolides
发明人：SMITH III AMOS B; SCHOW STEVEN R
权利人:UNIVERSITY PATENTS INC
摘要:Milbemycin and avermectin macrolides are synthesized by the cyclized linking of separately synthesized northern and southern hemisphere intermediates. The northern hemisphere intermediate is a spiroketal alkenyl aldehyde, and the southern hemisphere intermediate is an aryl alkenyl phosphine oxide anion.
