Abstract
A facile new method for the synthesis of 3,3-disubstituted phthalides is reported. A successive reaction process begins with the TfOH-catalyzed cyclization of o-alkynylbenzoic acids followed by an ortho-regioselective electrophilic alkylation of various electron-rich aromatic compounds or alkenes, which has been successfully developed. The corresponding regioselective products of 3-substituted phthalide were obtained in good to high yields.

Abstract
A palladium-catalyzed carbonylative cyclization reaction of 2-halidebenzaldehydes with H2O is described, which provides a strategy for the synthesis of diversely substituted 3,3'-oxyphthalides. Notably, the obtained 3,3'-oxyphthalide could be easily transformed into 3-aryl and alkyl phthalides with excellent efficiency using organozinc reagents under mild reaction conditions.

Abstract
Iodine is an element that exhibits characteristic features of heavy halogen, and
several compounds containing iodine constitute important synthetic intermediates due to
synthetically easy manipulation. To utilize iodine units for organic synthesis, a highly regio-
and stereoselective introduction of iodine to versatile building blocks is significant,
and a lot of research works for the selective introduction of iodine to alkynes or alkenes
have been conducted. In this review article, we describe regio- and stereoselective hydroiodination
to multiple bonds of building blocks, and its synthetic applications as key
intermediates to construct several important compounds in organic chemistry.

Abstract
A one-pot route for the synthesis of spiro-isobenzofuran compounds was developed via the condensation reaction of ninhydrin with 4-amino-1,2-naphthoquinones or 2-amino-1,4-naphthoquinones in acetic acid followed by the oxidative cleavage of the corresponding vicinal diols at room temperature. Various derivatives of spiro[benzo[g]indole-2,1'-isobenzofuran]-3,3',4,5(1H) tetraones and spiro[benzo[f]pyrrolo[2,3-h]quinoxaline-2,1'-isobenzofuran]-3,3'(1H)-diones were synthesized in good to high yields. Moreover, further condensation of spiro[benzo[g]indole-2,1'-isobenzofuran]-3,3',4,5(1H)-tetraones with 1,2-diamines resulted in the new spiro-isobenzofuran compounds having phenazine rings in high yields.

Abstract
We have provided a critical review that focuses on key developments in the area of 3-substituted phthalides and their role in the development of important biologically active natural products. 3-Substituted phthalides are vital molecules owing to their fascinating biological activity. The scope, isolation, and characterization of various naturally occurring racemic and chiral 3-substituted phthalides have been covered. We have put significant emphasis on recently developed research methodologies for the synthesis of racemic and chiral 3-substituted phthalides. These newer approaches are essential for the development of newer and elegant strategies for the synthesis of phthalide-based or similar molecular architecture with broader substrate scope and higher stereoselectivities. Also, we have discussed the application of 3-substituted phthalides as a precursor for the synthesis of natural products and their analogs. We have provided contextual information on the chemistry of 3-substituted phthalides and their significance in natural product synthesis.![]()
