Multitarget synthetic strategies to access novel photochromic 3H-naphtho[2,1-b]pyrans decorated with pyridyl units are described. The new pyridyl-substituted 3H-naphtho[2,1-b]pyrans display good photochromic properties with reversible generation of photomerocyanines, which exhibit mainly orange/red hues. Photochromic parameters including photocolorability and persistence of color vary tremendously on structural modification of the naphthopyran core.

A photocatalytic process for selective arylalkylation of allylic alcohols with α-bromo diethyl malonate has been developed. The reaction provided a straightforward approach to synthesize α-aryl-β-alkylated ketones via unique 1,2-aryl migration. The procedure is highlighted by its operational simplicity and mild reaction conditions.
