An environmentally friendly multicomponent reaction strategy for the synthesis of functionally rich all-carbon substituted 2,3-dihydro-1H-pyrrol-2-ols "in-water" at room temperature has been reported. Water plays an indispensable role in presence readily available catalytic surfactants sodium dioctylsulfosuccinate and dodecyl sulfate to effectuate transformation, as proved by inferior results obtained organic solvents. A wide display substrate scope functional group compatibility permits diversity generation a mild operationally simple fashion. High product yields, fast rate, recoverability/recyclability catalysts, high TON/TOF, ease purification final products filtration, AE values, excellent E-factor count with score low possible highlight "greenness" this approach. Feasibility "gram-scale" synthetic elaboration offer notable advantages. The mechanistic understanding intercepting labile "imine" intermediate realized through sequence imine formation Mannich-type followed intramolecular N-cyclization.

Modular C–N coupling is a desirable way to construct N-aryl carbamates, which are privileged scaffolds in active pharmaceutical ingredients. However, there no broadly applicable metal-free methods for theN-arylation of carbamates. Herein, we describe approach that uses aryl(TMP)iodonium salts as arylation reagents cyclic carbamates by exploiting the metal-like reactivity iodine(III). The scope includes 25 examples, including 17 different and 9 yields ranging between 55 97% (75% avg).
