Alkynyl sulfonamides undergo sequential 1,4- then 1,2-addition/rearrangement with lithium acetylides to yield enediynes in the absence of any promoters or catalysts. Mechanistic investigations suggest that reaction proceeds <italic>via</italic> a novel electrophilic carbenoid distinct reactivity compared those previously described.
ABSTRACT The use of biomass‐sourced chemical feedstocks creates a conflict over land between food and fuel/chemical production. Such could be reduced by making the annual 1.3 Pg waste resource. Oleic acid is available from seed oils such as pumpkin, grape, avocado mango. Its esterification with diols 1,3‐propanediol, resorcinol orcinol was used to form diesters naturally occurring norspermidine prepare diamide, all under ambient conditions. These compounds were then epoxidized polymerized....
