This disclosure describes certain hydroxy substituted 15-deoxy-5-cis-prostenoic acids and esters useful as hypotensive agents, anti-ulcer agents, bronchodilators, anti-microbial agents, anticonvulsants, or as intermediates.
A tandem oxidativecouplingreaction of β-ketoallenes and arenes was developed, which leads to the formation of 2-furylmethylarenes using AuCl3 and phenyliodine diacetate. The AuIII salt catalyzed the cyclization of β-ketoallenes to form a 2-furylmethyl gold intermediate, and the subsequent C–H functionalization of arenes proceeded smoothly. During the oxidativecoupling, nucleophilic additions occurred

A Cr-catalyzed enantioconvergent allenylation reaction of aldehydes with racemic propargyl halides has been developed. This robust method employs simple and readily accessible materials, exhibits exceptional functional group tolerance and broad substrate scope, and provides facile access to a wide range of valuable optically enriched α-allenols with two or three continuous chiral centers, including
