An efficient synthesis of halogen-substituted allenyl ketones via Ag-catalyzed oxidative ring opening of allenyl cyclic alcohols under mild reaction conditions has been achieved. The reaction features a wide substrate scope and excellent regioselectivity. The synthetic potential of the products has been demonstrated by their conversion to stereodefined alkenes and heterocyclic compounds.

with sp3-rich 3D-fragments and natural products. This is accomplished through a template-assisted inverse Sonogashirareaction that displays high levels of selectivity for the meta-position. This protocol is also amenable to distal structural modifications of α-amino acids. The transformation of alkyne functionality to other functional groups further highlights the applicative potential.

A facile and user-friendly protocol has been developed for the selective synthesis of E-vinyl silanes derived from propargylicalcohols using a PtCl2/XPhos catalyst system. The reaction is generally high yielding and provides a single regioisomer at the β-position with E-alkene geometry. The reaction is extremely tolerant of functionality and has a wide scope of reactivity both in terms of alkynes
An Unusual Conversion of 2‐(Alkynonyl)Alkynylbenzenes to Isocoumarins by a Retro‐Favorskii‐like Degradation

We report the discovery of an anomalous reaction of 2-(alkynonyl)alkynylbenzenes under AgI catalysis for the selective formation of isocoumarins. This reaction is previously undocumented for 2-(alkynonyl)alkynylbenzenes in terms of the reaction mechanism and the product formed. Water (H2 O18 ) labeling studies suggested a possible mechanistic pathway in which the initial formation of a pyrylium ion
