✦ Synopsis

The photocycloadditions of a series of chiral 3(2H)-l'uranones with alkenes show facial selectivilies which parallel the steric bulk of the furanone substituents.

Selectivities approaching 50: 1 are observed in some instances.

The photoaddition of alkenes to 2,2-dimethyl-3(2H)-furanone affords products which can be efficiently elaborated to cyclohexenones by two different methods. During the past several years we have been exploring the utility of acyclic a-formy ketones, particularly formyl acetone, as partners in the ph

## Abstract 3,4‐Dichloro‐2(5__H__)‐furanone, which has been prepared efficiently from mucochloric acid, has been transformed selectively into 4‐aryl‐3‐chloro‐2(5__H__)‐furanones either by Suzuki‐ or Stille‐type reactions. These monochloro derivatives have been used as precursors either to (__Z__)‐4
