For the first time, an enolate-mediated organocatalytic vinyl azide-carbonyl [3+ +2] cycloaddition (OrgVACC) of variousk etones/aldehydes with vinyl azides is reported. It is an efficient intermolecular reaction with excellent outcomes with reference to rate, yield, selectivity,o perational simplicity,s ubstrate scope, catalystsimplicity,a nd vast applications.

A new metal-free catalytic approach for the synthesis of anti-Markovnikov methyl acetals from vinylarenes based on in situ generated HOI species is reported. The mechanistic investigations provided the solid evidence for the proposed mechanism.
